ABSTRACT:
Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop, spring biased to an unlatched position, is latched to secure the close spring in the charged state by a latch assembly reset by a reset lever separate from the close prop which in turn is reset by rotation of the cam member during charging. An interlock prevents release of the close spring when the contacts are closed or the trip release is actuated. An indicator actuated by a driver pivoted against the cam shaft snaps from a DISCHARGED to a CHARGED indication as the close spring becomes fully charged and the driver drops into a notch created by a flat on the cam shaft. A snap action open/closed indicator for the switch contacts is also provided.
