Abstract
A circuit breaker crossbar assembly is provided and includes a crossbar rotatable between a first rotational position and a second rotational position, the crossbar is coupleable to at least one moveable contact arm of the circuit breaker. The circuit breaker crossbar assembly also includes an insert member disposed in communication with the crossbar and the at least one moveable contact arm to thereby exert a force on the at least one moveable contact arm.
Claims17
A circuit breaker crossbar assembly comprising:
- a crossbar rotatable between a first rotational position and a second rotational position, the crossbar coupled to at least one moveable contact arm of the circuit breaker;
- and
- an insert member disposed in communication with the crossbar and the at least one moveable contact arm operative to exert a force on the at least one moveable contact arm.
A circuit breaker comprising:
- a plurality of moveable contact arm assemblies configured to conduct current through the circuit breaker;
- a crossbar operatively coupled to the plurality of moveable contact arm assemblies, rotatable between a first rotational position and a second rotational position;
- a mechanism configured to selectively rotate the crossbar between the first and second rotational positions;
- and
- a plurality of insert members, each of the plurality of insert members coupled there between the crossbar and a respective moveable contact arm assembly, and arranged to exert a force on the respective moveable contact arm assembly.
A method of assembling a crossbar assembly for a circuit breaker comprising:
- coupling a portion of a moveable contact arm assembly to a crossbar, the moveable contact arm assembly selected from a plurality of distinct configurations of moveable contact arm assemblies;
- manufacturing an insert member having a customized configuration that is determined by a configuration of the moveable contact arm assembly coupled to the crossbar;
- and
- disposing an insert member between, and into communication with, the crossbar and the moveable contact arm assembly to thereby exert a force on the moveable contact arm.
