摘要： A shutter assembly is provided for an electrical system including at least one electrical switching apparatus, such as a circuit breaker, and a plurality of electrical bus members, and a plurality of electrical cable members, and a ground member with a plurality of contacts. Each of the conductors of the circuit breaker is removably coupled to a corresponding primary contact to electrically connect the circuit breaker to the electrical bus members and to electrically connect the circuit breaker to the electrical cable members and to electrically connect the circuit breaker to the ground members. The shutter assembly includes a flexible insulating member movably disposed between the conductors and the primary contacts. The flexible insulating member moves between a first position in which it provides access for the conductors to be coupled to the primary contacts, and a second position in which the flexible insulating member isolates and electrically insulates the bus member conductors from the primary contacts and the cable member conductors (“disconnected”) or isolates and electrically insulates the cable member conductors from the primary contacts and the ground member (“withdrawn”). An electrical switching apparatus and an electrical system employing the shutter assembly are also disclosed.

摘要： An energy storage and release control mechanism is provided for a stored energy assembly of an electrical switching apparatus. The stored energy assembly includes a shaft, a stored energy mechanism, and a charging mechanism, such as a charging cam. The charging cam is movable to pivot upon the shaft, thereby charging the stored energy mechanism. The energy storage and release control mechanism includes a ratchet coupled to the charging cam and including a plurality of teeth, a mounting assembly, and a plurality of pawl assemblies. Each pawl assembly includes a pawl pivoting between an engaged position corresponding to the pawl engaging the teeth of the ratchet to resist inappropriate movement of the charging handle, and a disengaged position corresponding to the pawl not engaging the teeth of the ratchet. Preferably, first and second pawl assemblies include first and second pawls, respectively, wherein only one of the first and second pawls engages the teeth of the ratchet at a time.
