Abstract
A circuit breaker, and method of assembling the circuit breaker, includes a circuit breaker housing defining an interior portion, and which includes a molded base and a separable cover. The molded base includes an interior surface and an exterior surface. The exterior surface of the molded base is operatively disposed outside of the interior portion of the circuit breaker housing, and the exterior surface of the base defines at least one current sensing unit receiving cavity configured to receive a current sensing unit therein. The molded base and separable cover are cooperatively disposed to surround the interior portion of the circuit breaker housing.
Claims17
A circuit breaker comprising:
- a circuit breaker housing defining an interior portion having a line-side and an opposing load-side, the circuit breaker housing comprising:
- a molded base having an interior surface and an exterior surface;
- and
- a separable cover coupled to the molded base;
- wherein the exterior surface of the molded base is disposed outside of the interior portion of the circuit breaker housing, the exterior surface of the molded base having a current sensing unit receiving cavity defined therein configured to receive a current sensing unit therein;
- wherein the depth of the line-side interior portion of the base is greater than the depth of the load-side interior portion of the base.
A molded case circuit breaker comprising:
- a molded base having an interior surface and an exterior surface;
- a separable cover coupled to the molded base, and cooperatively defining an interior portion therebetween;
- a conductive load strap corresponding to a respective pole of the circuit breaker disposed within the interior portion;
- wherein the exterior surface of the molded base is disposed outside of the interior portion, the exterior surface of the molded base having a current sensing unit receiving cavity defined therein, the current sensing unit receiving cavity configured to receive a current sensing unit therein;
- and
- a current sensing unit disposable within the at least one current sensing unit receiving cavity to operably surround the load strap without removal of the separable cover.
