摘要： A system and method for interrupting power in a three-phase power system interrupts power in the faulted phase and the next sequential phase at high speeds, while interrupting power in the remaining phase at a normal operation speed. Limiting high-speed interruption to only two phases requires significantly less energy storage than implementing high-speed interruption in all three phases. When hybrid circuit interrupters are used, the need to wait for a zero-crossing in the current signal in order to initiate interruption operations is eliminated.

摘要： A rotary switch includes a housing having an interior and an exterior, a plurality of moving contacts entirely disposed within the interior of the housing, a plurality of stationary contacts disposed partially within the interior of the housing and extending to an exterior of the housing, and a rotary element coupled to the plurality of moving contacts and being structured to rotate between a closed state where at least one of the plurality moving contacts contact a corresponding one of the plurality of stationary contacts and an open state where the plurality of moving contacts and the plurality of stationary contacts are separated.

摘要： An operating mechanism for a circuit breaker including an opening, first actuator assembly and a closing, second actuator assembly. The first actuator assembly is structured to operatively engage at least one movable contact and is structured to move the at least one movable contact from a first configuration to a second configuration. The second actuator assembly is structured to operatively engage the at least one movable contact and is structured to move the at least one movable contact from the second configuration to the first configuration. The first actuator assembly and the second actuator assembly are split cooperative actuator assemblies.

摘要： A disc member is for a Thomson coil actuator of an electrical switching apparatus. The Thomson coil actuator has at least one generally planar coil. The disc member includes at least one annular-shaped conductive member structured to be driven by the coil, and a structural support member directly coupled to the conductive member.

摘要： A hybrid switch assembly for use in a circuit interrupter, the hybrid switch assembly including an input, an output, separable contacts electrically connected between the input and the output, a solid state switching circuit electrically connected between the input and the output and in parallel with the separable contacts, and a fuse electrically connected in series with the solid state switching circuit. The solid state switching circuit is structured to turn on and allow current to flow through it between the input and the output for a predetermined amount of time after the separable contacts separate.
