Patent ID: 8587392

Claim:
A mechanism-operated cell (MOC) operator structure for a circuit breaker, the circuit breaker including an operating mechanism that closes main contacts of the circuit breaker, the MOC operator structure being associated with an interface structure for controlling auxiliary switches, the MOC operator structure comprising: linkage structure constructed and arranged to be coupled between the operating mechanism and the interface structure, an armature associated with the linkage structure, and permanent magnet structure associated with the circuit breaker and disposed generally adjacent to the armature, wherein, when the operating mechanism is coupled with the linkage structure and at least a part of the operating mechanism moves in a first mechanism direction, a portion of the linkage structure moves in a first linkage direction and moves the MOC operator structure to an open position, with the armature being magnetically engaged with the permanent magnet structure to maintain the MOC operator structure in the open position, and when the portion of the operating mechanism moves in a second mechanism direction, the portion of the linkage structure moves in a second linkage direction and moves the MOC operator structure to a closed position, with the armature magnetically disengaging from the permanent magnet structure.
