A flow chart 1500 of software functions include four subroutinesA, B, C, D 1502(1-4). At step 1505 an amp rating is determined. If a decision is no N meaning it is unknown at step 1507 then the process ends and initiates the subroutine C 1502(3). If a decision is yes Y meaning it is programmed at step 1509 then the process checks contact status in step 1511. If the contact status is open at step 1513 the subroutine D 1502(4) is to be executed. Then a self test pass check is made a step 1515. If not (N) pass then the subroutine C 1502(3) is executed. If pass is yes Y a current level check is made at step 1517. If the contact status is closed at step 1519 then a self test pass check is made at step 1521. If not (N) pass then the subroutine C 1502(3) is executed. If pass is yes Y a current level check is made at the step 1517.

(54) From the current level in step 1517, check an instantaneous level in step 1523. If the instantaneous level is below 10 then run the subroutine A 1502(1). However, if the instantaneous level is above 10 then run the subroutine B 1502(2). From the current level in step 1517, check an overload status in step 1525. If the overload status is below 1.25% then run the subroutine A 1502(1). However, if the overload status is above 1.25% then run the subroutine B 1502(2).

(55) The subroutine A 1502(1) includes a status indicator step 1530 and a step of displaying 1532 as On, Current or Voltage. Next a send signal step 1535 sends a signal via a network 1537 such as Internet to a phone APP in step 1540. A display status On is displayed in step 1542.

(56) The subroutine B 1502(2) includes in step 1545 a mag-latch is activated to open main contacts. In step 1547, the device overcomes a torsion spring force. Then in step 1550, the status indicator changes states. Next is a step of displaying 1552 as Off, --, --. Next via the network 1537 such as Internet the subroutine B 1502(2) sends a signal to a phone APP in step 1554. A display status Off is displayed in step 1555.

(57) The subroutine C 1502(3) includes in step 1557 a mag-latch is activated to open main contacts. In step 1559, the device overcomes a torsion spring force. Then in step 1560, the status indicator changes states. Next is a step of displaying 1562 as error message. Next via the network 1537 such as Internet the subroutine C 1502(3) sends a signal to a phone APP in step 1564. A display status error message is displayed in step 1565.

(58) The subroutine D 1502(4) includes in step 1567 a mag-latch is activated to close main contacts. In step 1569, the main contacts of the smart and the hybrid circuit breaker 5 close. Next is a step of displaying 1572 as On, Current or Voltage. Next via the network 1537 such as Internet the subroutine D 1502(4) sends a signal to a phone APP in step 1574. A display status On is displayed in step 1575.

(59) In operation, once the smart and the hybrid circuit breaker 5 is activated the software module will make several decisions on the initial status of the smart and the hybrid circuit breaker 5. First step is to determine if a micro SD card is installed and the amp rating for the smart and the hybrid circuit breaker 5 is defined. If no SD card is installed, then the smart and the hybrid circuit breaker 5 starts the subroutine C 1502(3). In the subroutine C 1502(3), the mag-latch 230 receives a 24 VDC signal for 25 milliseconds in the event that the main contacts are closed. This increases the magnetic field strength and attracts the mag-latch plunger. This magnetic force will overcome the torque applied from the torsion spring to the moveable arm with contact. The moveable contact arm rotates clockwise and separates the main contacts. A predetermined message is displayed in the display screen to alert the consumer. This same message is sent to the cell phone APP application thru Wi-Fi and a receiver in the cell phone. If the main contacts are already open, the predetermined message is sent.

(60) If a SD card is installed, the software module determines if the main contacts 430 are closed or open. In the event that the main contacts 430 are closed, a self test is conducted to ensure that the electronics are working properly. If the self test passes, the current level is monitored and checked for a thermal overload and/or whether an instantaneous condition exists. If the thermal overload is determined to be 1.25% and/or the instantaneous levels are below 10 the smart and the hybrid circuit breaker 5 rating, the subroutine A 1502(1) is started. Under these conditions, a predetermined message is displayed on the display screen to indicate the smart and the hybrid circuit breaker 5 is ON along with the current and voltage that is being applied to the smart and the hybrid circuit breaker 5. This same message is sent to the cell phone APP application thru Wi-Fi and a receiver in the cell phone.

(61) If the thermal overload is higher than 1.25% and/or the instantaneous levels are higher than 10x of the smart and the hybrid circuit breaker 5 rating, the subroutine B 1502(2) will be initiated. In this routine, the mag-latch 230 is activated with a 24 VDC signal to open the main contacts 430. This increases the magnetic field strength and attracts the mag-latch plunger. This magnetic force will overcome the torque applied from the torsion spring to the moveable arm with contact. The moveable contact arm rotates clockwise separates the main contacts 430. A predetermine message is displayed on the display screen to indicate the smart and the hybrid circuit breaker 5 is OFF along with no current and voltage being applied. This same message is sent to the cell phone APP application thru Wi-Fi and a receiver in the cell phone.

(62) In the event that the main contacts 430 are open, the subroutine D 1502(4) is initiated. A 24 VDC signal is sent to the mag-latch for less than 5 milliseconds. This decreases the magnetic field strength and allows the contact arm with contact to rotate counterclockwise to close the main contacts 430. Once the main contacts 430 are closed, a self test is conducted. If the self test passes, the current level is monitored and checked for a thermal overload and/or whether an instantaneous condition exists. If the thermal overload is determined to be 1.25% and/or the instantaneous levels are below 10x the smart and the hybrid circuit breaker 5 rating, the subroutine A 1502(1) is started. In the event if the thermal overload is higher than 1.25% and/or the instantaneous levels are higher than 10x of the smart and the hybrid circuit breaker 5 rating, the subroutine B 1502(2) will be initiated. In this routine, the mag-latch 230 is activated with a 24 VDC signal to ensure that the main contacts 430 are open. Depending on the subroutine initiated, a predetermined message is displayed on the display screen to indicate the smart and the hybrid circuit breaker 5 is ON or OFF along with the current and voltage that is being applied to the smart and the hybrid circuit breaker 5. This same message is sent to the cell phone APP application thru Wi-Fi and a receiver in the cell phone.

(63) FIG. 16 illustrates the smart or the hybrid circuit breaker 5 turning ON or OFF from a cell phone application (APP) 1600 in accordance with an exemplary embodiment of the present invention. At the cell phone APP 1600, in step 1602 a breaker is selected. Then at step 1605 a user can turn ON or OFF the smart or the hybrid circuit breaker 5. The cell phone APP 1600 on a network 1607 such as Internet via Wi-Fi sends a signal to the smart or the hybrid circuit breaker 5. If in step 1610(1) the signal is turn ON the subroutine D 1502(4) is executed. However, if the signal is turn OFF in step 1610(2) the subroutine C 1502(3) is executed. After the run of the subroutine D 1502(4) at the step 1505 an amp rating is determined. Next the flow of the flow chart 1500 of FIG. 15 is followed.

(64) In operation, once the selection to turn the smart or the hybrid circuit breaker 5 ON is selected, a signal is sent from the cell phone APP 1600, thru Wi-Fi and to the smart or the hybrid circuit breaker 5. The subroutine D 1502(4) is initiated. A 24 VDC signal is sent to the mag-latch 230 for less than 5 milliseconds. This decreases the magnetic field strength and allows the contact arm 243 with contact to rotate counter-clockwise to close the main contacts 430. Once the main contacts 430 are closed, the software module determines the amp rating for the smart or the hybrid circuit breaker 5 from a micro SD card. A self test is conducted. If the self test passes, the current level is monitored and checked for a thermal overload and/or whether an instantaneous condition exists. If the thermal overload is determined to be 1.25% and/or the instantaneous levels are below 10x the smart or the hybrid circuit breaker 5 rating, the subroutine A 1502(1) is started. In the event. If the thermal overload is higher than 1.25% and/or the instantaneous levels are higher than 10x of the smart or the hybrid circuit breaker 5 rating, the subroutine B 1502(2) will be initiated. In this routine, the mag-latch 230 is activated with a 24 VDC signal to open the main contacts 430. Depending on the subroutine initiated, a predetermine message is displayed on the display screen to indicate the smart or the hybrid circuit breaker 5 is ON or OFF along with the current and voltage that is being applied to the smart or the hybrid circuit breaker 5. This same message is sent to the cell phone APP 1600 thru Wi-Fi and a receiver in the cell phone. If no SD card is installed then the software module starts the subroutine C 1502(3). In the C subroutine, the mag-latch 230 receives a 24 VDC signal for 25 milliseconds. This increases the magnetic field strength and attracts the mag-latch plunger. This magnetic force will overcome the torque applied from the torsion spring to the moveable arm with contact. The moveable contact arm rotates clockwise and separates the main contacts 430. A predetermined message is displayed in the display screen to alert the consumer.

(65) To turn the smart or the hybrid circuit breaker 5 OFF, the OFF selection is made using the cell phone APP 1600. A signal is sent from the cell phone, through Wi-Fi and to the smart or the hybrid circuit breaker 5. The subroutine C 1502(3) will be initiated. In the C subroutine, the mag-latch 230 receives a 24 VDC signal for 25 milliseconds. This increases the magnetic field strength and attracts the mag-latch plunger. This magnetic force will overcome the torque applied from the torsion spring to the moveable arm with contact. The moveable contact arm rotates clockwise and separates the main contacts 430. A predetermined message is displayed in the display screen to alert the consumer. This same message is sent to the cell phone APP 1600 through Wi-Fi and a receiver in the cell phone.

(66) FIG. 17 illustrates a self-test setup for the smart or a hybrid circuit breaker 5 in accordance with an exemplary embodiment of the present invention. Main contacts 1705 are provided between a line 1707 and a load 1710 across a neutral 1712. A display screen 1715 is provided. A module 1720 includes a self-test module 1722 and an electronic detection module 1725. The self-test module 1722 is connected to a mag-latch 1727 and the electronic detection module 1725 is connected to a Wi-Fi module 1730. A signal 1735 is sent by the module 1720.

(67) In operation, the smart or a hybrid circuit breaker 5 begins to conduct self-test and/or arc detection once installed. If the self-test does not pass or an arc is detected on the line 1707, a 24 VDC is not sent to the mag-latch 1727 to close the circuit. If the smart or a hybrid circuit breaker 5 is closed and a self-test non-conforms, an arc is detected on the line 1707, overload and/or high instantaneous condition exists, a signal is sent to the mag-latch 1727 to open the circuit. In either condition, a microprocessor would send a signal to the Wi-Fi module 1730 to display a message to the display screen 1715 and indicate On to Open condition. In the algorithm, preset error messages would be programmed based on the various methods of tripping. In addition, a signal is sent to the Wi-Fi module 1730 and subsequently received by a cell phone receiver. The same message is displayed in a cell phone application (APP).

(68) FIG. 18 illustrates the smart or a hybrid circuit breaker 5 mechanism in an ON position in accordance with an exemplary embodiment of the present invention. A mag latch plunger 1805 is shown in an extended position. A mag-latch 1807 receives a 24 VDC signal that is initiated from several conditions. The signal can be triggered due to a signal from the cell phone APP or a by pressing a Push-To-Test button (PTT) 1810. Algorithm in a microprocessor would include pre-setting to display a message for either of these conditions. Using the cell phone APP, a signal would be transmitted to a Wi-Fi module to initiate a signal to the mag-latch 1807. As an alternate, a Push-To-Test event would also send a signal to the mag-latch 1807 that would open the circuit. Once either of these conditions is met, a 24 VDC signal is sent to the mag-latch 1807 for less than 5 milliseconds. This decreases the magnetic field strength and allows a torsion spring 1812 to rotate a contact arm or a movable arm with a contact 1815 counter-clockwise. The contact arm with contact 1815 rotates about a pivot pin 1817. The pivot pin 1817 can be made of stainless steel material while the contact arm could be made of a copper alloy such as CDA260. The torsion spring 1812 applies a 1.410.1 inch-pound torque to the moveable arm with contact. The moveable arm with contact rotation is stopped when the moveable arm with contact touches a stationary terminal with contact 1820. Once the current path has been completed, a message would be sent to a display screen and would switch from Open to On. In the algorithm, preset messages would be programmed based on the circuit closing. A signal is sent to the Wi-Fi module and subsequently received by a cell phone receiver. The same message is displayed in the cell phone APP.

(69) FIG. 19 illustrates the smart or a hybrid circuit breaker 5 mechanism in an OFF position in accordance with an exemplary embodiment of the present invention. The mag latch plunger 1805 is shown in a retracted position. The mag-latch 1807 receives a 24 VDC signal that is initiated from several conditions. The signal can be triggered due to Arc Fault or Ground Fault condition, self test non-conformance, thermal over load, high instantaneous, signal from the cell phone APP application, and/or a by pressing the Push-To-Test button (PTT) 1810. An overload condition would be controlled in an algorithm and could be set at 1.258% times the circuit breaker rating. An instantaneous condition would be controlled in the algorithm and could be set at 8-10 times the circuit breaker rating. The circuit breaker rating would be determined by the number of contacts exposed on a micro SD card. Alternate means of determining the circuit breaker rating could be The PCBA (printed circuit board assembly) to include a microprocessor with software that will communicate with the Wi-Fi module). The Wi-Fi module in the cell phone or computer will send a signal of what amperage rating to use in the smart or a hybrid circuit breaker 5 and that will be received by the breaker PCB Wi-Fi receiver and send a signal to the software to program the smart or a hybrid circuit breaker 5 amperage. A third option to determine the circuit breaker rating could be that the amperage rating of the breaker is adjusted directly to the breaker from where the breaker will have some feature(s) where the end user can adjust the amperage rating directly in the device and a mechanical/electronic interface located in the PCB that will send the signal to the PCB software. Once any of these conditions are met, a 24 VDC signal is sent to the mag-latch 1807 for 25 milliseconds. This increases the magnetic field strength and attracts the mag-latch plunger 1805 with a force of 5.00.2 pounds. This magnetic force will overcome the torque applied from the torsion spring 1812 to the moveable arm with contact 1815. The moveable arm with contact 1815 rotates clockwise about the pivot pin 1817 and therefore separates the contacts. The pivot pin 1817 can be made of stainless steel material while the contact arm could be made of a copper alloy such as CDA260. Once the current path has been broken, a message would be sent to the display screen that would switch from On to Open. In the algorithm, preset messages would be programmed based on the various method of tripping. In addition, a signal is sent to the Wi-Fi module and subsequently received by the cell phone receiver. The same message is displayed in the cell phone APP.
