A device for door and phase segregation in low voltage circuit breakers, in particular in molded case circuit breakers, having a plurality of phases each provided with a lug for electrical connection of said circuit breaker and a venting aperture for venting off gases, the device comprising a conductive element adapted to be fixed to a corresponding lug of the circuit breaker and provided with electrical connection means for electrical connection of the circuit breaker, comprising a first insulating element covering the conductive element and/or a second insulating element adapted to be interposed between two adjacent phases of the circuit breaker.

An improved interruption apparatus includes a plurality of poles, with each of the poles including an actuator. In one embodiment, the actuator can be a fuse having a movable engagement element, and in another embodiment the actuator can be an electric coil that is operable to move a movable engagement element. The interruption apparatus has a single trip unit, and the engagement element of any actuator can actuate the trip unit to move all of the poles from a CLOSED state to an OPEN state.

Systems and methods for providing end-of-life functionality in an electrical component using a count of plugging operations are shown. In some configurations, a GFCI counts plugging operations and then provides an LED end-of-life indication when a threshold of plugging operations is met.

Circuit breakers with handles having at least one handle bearing pin that contacts an upper end portion of a moving arm and allows the arm to rotate to OFF, ON and TRIP positions, typically about 90 degrees of rotation.

An electromagnetic relay includes an electromagnet device, a contact device, and a trip device. The electromagnet device includes a first stator, a movable element, and a first exciting coil. The contact device includes a movable contact and a fixed contact. A trip device includes a second exciting coil. The electromagnet device moves the movable element from a first position to a second position. The trip device moves the movable element to a third position. An open state is reached when the movable element is in the first position and the third position. A closed state is reached when the movable element is in the movable element is in the second position.

Power outlets adapted for installation within an enclosure are provided. Power outlets are provided having a safety interlock adapted to prevent the creation of a hazardous condition within the enclosure as a result of the continued operation of an electrical device within the enclosed space. The safety interlock may include current limiting circuitry and hardware, hazard sensing devices interconnected with such current limiting circuitry and hardware or other circuit breaker switches, and combinations of such safety interlocks.
