摘要： A circuit breaker for a multi-pole electrical distribution circuit includes a cassette associated with each pole in the multi-pole electrical distribution circuit. Each cassette includes a housing, a pair of electrical contacts disposed in the housing, and a thermal and magnetic trip unit supported by the housing. The housing includes a first compartment having the electrical contacts disposed therein and a second compartment having at least a portion of the thermal and magnetic trip unit disposed therein. A wall separates the first and second compartments for isolating the second compartment from gasses generated by separation of the first and second contacts. A duct adjacent to the second compartment allows the gasses to pass to an exterior portion of the housing. The housing includes a pair of opposing slots formed therein for receiving edges of a load terminal. A lever has a first end disposed proximate an end of a bimetallic element and a second end disposed proximate an armature in the magnetic assembly of the trip unit. The lever is rotated by at least one of the bimetallic element and the armature to unlatch an operating mechanism.

摘要： A trip system for a circuit breaker having a support frame, a trip unit, a crossbar, and a trip bar, is disclosed. The trip unit is responsive to an electric current for generating a trip force, the crossbar is directly coupled to the trip unit and to the support frame, and the trip bar is directly coupled to the support frame. The electric current at the trip unit generates a trip force that acts upon the trip bar to trip the circuit breaker. The crossbar remains substantially stationary during the tripping action.

摘要： A trip system for a circuit breaker having a calibration system is disclosed. The calibration system includes a retainer, a tripping member responsive to an electric current, an actuator retained by the retainer, a spring adjuster adjustably engaged with the actuator and the tripping member, and a bias spring disposed for biasing the actuator in a first direction. Movement of the spring adjuster absent movement of the actuator and the tripping member results in a change in the bias spring force and no change in the position of the tripping member, and movement of the tripping member absent movement of the spring adjuster results in a change in the position of the tripping member and no change in the bias spring force.
