A circuit breaker includes a crank for coupling a rotary arm breaker mechanism to the cradle. The crank has a protrusion which cooperates with a handle yoke to restrict movement of the operating handle when the contacts of the circuit breaker are welded. The crank protrusion is arranged such that it does not interfere with the handle under normal operating conditions.

An electrically isolated rotor assembly for a cassette assembly of a circuit breaker includes a rotor having a first side and an opposing second side, a first isolation cap disposed on the first side, a second isolation cap disposed on the second side. Each isolation cap preferably includes a centrally located knob with a bushing surrounding each knob, wherein the bushings are sized for securement within apertures within first and second cassette half pieces.

A molded insulator cover for a circuit breaker molded case includes a terminal connector attachable to the strap terminal. The terminal connector is disposed in the circuit breaker molded case and an insulator discrete from the molded case is disposed around the terminal connector. The insulator is trapped into the circuit breaker molded case by attachment of the terminal connector to the strap terminal. The insulator is configured to be used with a plurality of different field installable terminal connectors.

An adjustable solenoid having an enclosure containing a winding through which a current is passed. The winding defines an area and a plunger is positioned at one end of the area with a mechanical biasing mechanism for providing a biasing force to the plunger, the mechanical biasing mechanism is secured to the plunger at one end and a support at the other end. A stator having a first threaded portion engaged within a threaded opening of the enclosure causes the stator to travel between a first position and a second position as a rotational force is applied to the stator. The first position is closer to the plunger than the second position, and the stator is in a facially spaced relationship with respect to the plunger and the stator has a second threaded portion for engaging a threaded portion of the support, the second threaded portion of the stator causes the support to travel between a first position and a second position, the second position of the support provides the mechanical biasing mechanism with a greater biasing force than the first position.
