A system for electrically operating a circuit breaker remotely and during period of a power outage is provided. The system has a power source, power cable, control unit, control device, and a circuit breaker port for connecting the power source and control unit to the circuit breaker, for actuation of the circuit breaker operating mechanism.

The invention relates to an electrical switch device comprising contacts which are mobile through actuation of a first rotation shaft (10) and a control mechanism (1) for the mobile contacts which is situated in a housing and which can be rearmed via a second rotation shaft (20). The first rotation shaft (10) passes through a first wall (2, 3) of the housing and the device comprises a first rotation sensor (12) coupled with the first rotation shaft (10) outside of the housing, so as to measure the angular displacement of the first rotation shaft. The second rotation shaft (20) passes through a second wall (2, 3) of the housing and the device comprises a rearming module (25, 26) removably fixed outside of the housing against the second wall (2, 3), so as to be coupled with the second rotation shaft (20) to be able to rearm the control mechanism.

A low voltage circuit breaker is provided. The low voltage circuit breaker includes a contact system with a first contact and a second contact that are electrically connectable and disconnectable relative to one another. The first contact includes a body having a first layer and a second layer, wherein the first layer is arranged on the second layer and is configured to come in contact with the second contact for providing the electrical connection with the second contact. The first layer has a first material composition having an Ag content that is higher than an Ag content of a second material composition of the second layer. Further, the first material composition has a WC content that is lower than a WC content of the second material composition.

There is a need in homes and small businesses for simple devices to help residents in emergency situations. Extended power outages are an example. SAVUS is a simple, safe, low cost device to connect emergency power to an entire home. Current emergency power solutions are costly and usually require complex installation. SAVUS has models which install into most residential type circuit breaker front panels and require only one available circuit breaker space for installation. SAVUS mechanically interlocks with the main circuit breaker and will not allow connection of an external power source to the circuit breaker box until utility power is turned off for safety. Because it is on the house side of the main circuit breaker and completely enclosed with other circuit breakers, utility approval is not normally required. We believe SAVUS may become nearly as common in homes as smoke detectors.

In one embodiment, there is a fault interrupter device comprising at least one sensor comprising at least one first transformer having at least one outer region forming an outer periphery and at least one inner hollow region. There is also at least one second transformer that is disposed in the inner hollow region of the at least one first transformer. The transformers can be substantially circular in configuration, and more particularly, ring shaped. In another embodiment there is a rotatable latch which is used to selectively connect and disconnect a set of separable contacts to selectively disconnect power from the line side to the load side. The rotatable latch is in one embodiment coupled to a reset button. In at least one embodiment there is a slider which is configured to selectively prevent the manual tripping of the device.

This disclosure relates to various embodiments of lockout relay devices. In one embodiment, a lockout relay device may transition between a closed position and a lockout position in response to an action of a deck device. The lockout relay may further be configured to transition from the lockout position to the closed position only in response to one of a manual adjustment and a reset operation. A manual actuator may permit a manual transition of the lockout relay device from the closed position to the lockout position and from the lockout position to the closed position. The lockout relay device may remain in the lockout position until the occurrence of one of a manual adjustment and a reset operation.
