摘要： An electromagnetic switch protection structure includes a power-off key located between a press assembly and a contact seat. The power-off key is provided with a press portion extending downward. The press portion directly presses an elastic seat of the electromagnetic switch. When a power-off button is pressed, movable contacts of the elastic seat can be immediately separated from immovable contacts of electrode plates to cut off the power supply of the electromagnetic switch. That is, the press assembly is slightly touched to cut off the power supply, not pressing deep to cause an erroneous pressing, to avoid damage to the electromagnetic switch, achieving the protection of the electromagnetic switch.

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： A circuit breaker comprises a latching plate rotatably coupled to a moveable plate, and tensile type latching springs, each latching spring having two ends fixed to the latching plate and the moveable plate, respectively. Time taken for a moveable contact to be lifted up from a contact time point between the moveable contact and a fixed contact may be shortened, and thus a time duration for which an accident current flows may be reduced. Accordingly, the amount of energy applied to the circuit breaker may be reduced, and a breaking function of the circuit breaker may be enhanced. Furthermore, since a contact pressure between the moveable contact and the fixed contact has a constant change, a reliability on a conductive state of the moveable contact and the fixed contact may be enhanced.
