Abstract
A circuit breaker assembly is disclosed. The assembly includes a base having an interior bottom surface that includes a first engagement feature and a circuit breaker cassette having an exterior bottom surface that includes a second engagement feature. The cassette is oriented in the base to provide for a current path through the base in a first direction. The first engagement feature engages with the second engagement feature and restrains movement of the cassette relative to the base in a second direction that is perpendicular to the first direction and parallel to the interior bottom surface.
Claims16
A circuit breaker assembly comprising:
- a base having an interior bottom surface comprising a first engagement feature;
- and
- a circuit breaker cassette having a bottom surface with a perimeter, the cassette also having an exterior bottom surface comprising a second engagement feature, the cassette being oriented in the base to provide for a current path through the base in a first direction;
- wherein the first engagement feature engages with the second engagement feature and restrains movement of the cassette relative to the base in a second direction that is perpendicular to the first direction and parallel to the interior bottom surface, the first engagement feature being disposed to lie within the perimeter of the bottom surface of the cassette;
- wherein the circuit breaker assembly is a three phase circuit breaker assembly comprising three circuit breaker cassettes oriented side by side within the base to define left pole, center pole, and right pole cassettes, and the interior bottom surface of the base comprises two first engagement features disposed corresponding to the left pole and right pole cassettes.
A circuit breaker assembly comprising:
- a base having an interior bottom surface comprising a protrusion extending from the interior bottom surface;
- and
- a circuit breaker cassette having a bottom surface with a perimeter, the cassette also having an exterior bottom surface comprising an engagement feature, the cassette being oriented in the base to provide for a current path through the base in a first direction;
- wherein the protrusion engages with the engagement feature and restrains movement of the cassette relative to the base in a second direction that is perpendicular to the first direction and parallel to the interior bottom surface, the engagement feature being disposed to lie within the perimeter of the bottom surface of the cassette;
- wherein the circuit breaker assembly is a three phase circuit breaker assembly comprising three circuit breaker cassettes oriented side by side within the base to define left pole, center pole, and right pole cassettes, and the interior bottom surface of the base comprises two first engagement features disposed corresponding to the left pole and right pole cassettes.
