Abstract
An operating mechanism operates a multi-pole circuit breaker assembly. For each circuit breaker in the multi-pole circuit breaker assembly, the following elements are provided: a connection assembly for connection to an operating shaft of the circuit breaker, an actuator for changing between an ON and OFF state of the operating mechanism, a translation assembly for transferring a movement of the actuator to the connection assembly, and a compression spring exerting a force on the operating shaft in the ON state of the operating mechanism. The force exerted by the compression spring is adjustable by a force setting assembly in a continuous manner.
