A circuit interrupter includes separable contacts, a drive shaft coupled to the separable contacts and structured to move to open and close the separable contacts, a tapered drive shaft section coupled to the drive shaft and having tapered sides, and a friction assembly. The friction assembly includes a friction device structured to interact with the tapered sides of the tapered drive shaft, an armature coupled to the friction device, and a biasing member structured to bias the friction device and armature toward the tapered drive shaft section.

A manual opening mechanism for use with an isolation switch of a circuit interrupter is fully integrated into the circuit interrupter. The manual opening mechanism includes a rotating handle that is accessible from the front panel of the circuit interrupter. Rotating the handle applies force to the centerline of the isolation switch drive shaft, which prevents uneven loading and thus optimizes robustness during manual opening of the isolation switch. In addition, the handle has an ergonomic design, and is proportioned to minimize the force that an operator must apply to the handle in order to open the isolation switch.

A damping and latching mechanism for a Thomson coil-based actuator used to open and close the separable contacts of circuit interrupters in circuit breakers uses magnetorheological fluid to actively control the damping of opening and closing strokes in a circuit breaker in order to decrease wear and tear on components that can result from contact-based damping mechanisms and to maintain the open and closed states of separable contacts in the circuit breaker.

An interlock system includes a number of lock assemblies and a number of keys. Each key is associated with at least one lock assembly. The number of lock assemblies includes a number of actuator lock assemblies and a number of multi-purpose lock assemblies. The number of keys includes a number of actuator keys and a number of multi-purpose keys. At least one lock assembly is operatively coupled to a reliable indicator.
