摘要:
A levering assembly is provided for an electrical switching apparatus, such as a circuit breaker, which is removably disposed in a cassette. The levering assembly includes a mounting member coupled to the housing of the circuit breaker. A drive assembly is coupled to the mounting member and cooperates with the cassette. A powered actuator, such as an electric motor, is disposed on the mounting member and actuates the drive assembly to move the circuit breaker with respect to the cassette. The powered actuator is disposed within the housing of the circuit breaker. The mounting member, drive assembly and powered actuator form a self-contained sub-assembly, which is substantially disposed behind the circuit breaker cover. The levering assembly is operable from a remote location to automatically move the circuit breaker with respect to the cassette, to provide enhanced safety among other benefits.
