A levering assembly (100) is provided for an electrical switching apparatus, such as a circuit breaker (2), which is removably disposed in a cassette (300). The levering assembly (100) includes a mounting member (102) coupled to the housing 5 (4) of the circuit breaker (2). A drive assembly (112) is coupled to the mounting member (102) and cooperates with the cassette (300). A powered actuator, such as an electric motor (114), is disposed on the mounting member (102) and actuates the drive assembly (112) to move the circuit breaker (2) with respect to the cassette (300). The powered actuator (114) is disposed within the housing (4) of the circuit breaker (2). The mounting 10 member (102), drive assembly (112) and powered actuator (114) form a self-contained sub-assembly (100), which is substantially disposed behind the circuit breaker cover (14). The levering assembly (100) is operable from a remote location to automatically move the circuit breaker (2) with respect to the cassette (300), to provide enhanced safety among other benefits. |
