摘要： A GFCI device includes a latch assembly provided with a rigid electrically conducting bar connected thereto such that when a user presses a reset button the latch assembly is moved toward a pair of contacts provided as part of a reset circuit to initiate a reset operation. When the electrically conducting bar on the latch assembly connects the pair of contacts, the reset circuit is closed and an actuator is activated to place the GFCI device in the latched, reset, condition. If the GFCI device is correctly wired, the latch assembly enters the latched state. If the device is not properly wired no power is provided to the actuator and the device remains in the tripped, or open, state.

摘要： Equipment protection systems, arc containment devices, and methods of assembling arc containment devices are disclosed. In one example, an electrical isolation structure includes a conductor base, a cover coupled to the conductor base and defining an isolation chamber, a containment shield disposed on the conductor base within the isolation chamber, and a biasing assembly positioned between the cover and the containment shield. The containment shield defines a containment chamber configured to enclose the plurality of electrode assemblies. The containment shield is configured to at least partially contain the arc products within the containment chamber. The biasing assembly is configured to permit the containment shield to move away from the conductor base to thereby define a gap between the conductor base and the containment shield to enable at least some of the arc gases to vent from the containment chamber.

摘要： Disclosed are various embodiments for a portable actuator for actuating a trip button and a close button of a circuit breaker. In one embodiment, the trip button is actuated by a linear actuator that transmits rotation forces produced by a motor to the trip button in response to a trip signal. The close button is actuated by a rotating arm that uses an anti-friction roller to apply a rotating motion to the close button in response to a close signal. The portable actuator is configured to receive the input signals from a remote location with a remote controller that is in electronic communication with the portable actuator.
