Abstract
The present invention discloses a three position interlocking module for circuit breaker. In particular, a three position interlock module for a withdrawable circuit breaker to eliminate any chance of malfunction with respect to the circuit breakers operation (Test, Service And Transit) and its associated equipment?s in the system like LV plug, Earthing switch, panel door or switchgear access. It is easily replaceable on site thereby giving a reliable retrofit option. The three position interlocking module (3) comprises a three-position interlock knob (1), a three-position interlock socket (2) adaptively coupled to the interlock knob (1) for driving the module (3), an interlock shaft (5) disposed within a circuit breaker locking plate (4) to connect the circuit breaker to the interlock knob (1) and an interlock knob shaft (11) operably coupled to the interlock knob (1) to actuate the three-position interlock socket (2). The interlock knob (1) allows a user to select any one of the three interlock positions, i.e., Test, Service And Transit. The most illustrative drawing: Fig. 3
