Abstract
A circuit breaker is provided and includes a cassette, including a housing surface, a cassette-side terminal block attached to the cassette, including terminal housings arrayed thereon, being rotatable about the housing surface, a circuit breaker configured to be removably inserted into the cassette during a rack-in operation, and a circuit breaker-side terminal block attached to the circuit breaker with terminal housings arrayed thereon.
Claims20
A circuit breaker apparatus, comprising:
- a cassette, including a housing surface;
- a cassette-side terminal block rotatably attached to the housing surface of the cassette, including first terminal housings arrayed thereon, and being rotatable between at least a first position and a second position;
- a circuit breaker configured to be removably inserted into the cassette during a rack-in operation;
- and
- a circuit breaker-side terminal block attached to the circuit breaker with second terminal housings arrayed thereon to positionally cooperate with the first terminal housings when the cassette-side terminal block is in the first position and when the rack-in operation is at least partially complete.
A circuit breaker apparatus, comprising:
- a cassette having an external structure, including a housing surface;
- a cassette-side terminal block attached to the housing surface via a hinge about which the cassette-side terminal block rotates between at least a service position thereof and a wiring position thereof;
- a set of female terminal housings arrayed on the cassette-side terminal block;
- a circuit breaker configured to be removably inserted into a connected position with the cassette during a rack-in operation;
- a circuit breaker-side terminal block attached to the circuit breaker;
- and
- a set of male terminal housings arrayed on the circuit breaker-side terminal block to positionally cooperate with the female terminal housings when the cassette-side terminal block is in the service position and when the rack-in operation is at least partially complete.

- a set of female terminal housings arrayed on the cassette-side terminal block;
- a circuit breaker configured to be removably inserted from a disconnected position and into at least a test position and a connected position with the cassette during a rack-in operation;
- a circuit breaker-side terminal block attached to the circuit breaker;
- and
- a set of male terminal housings arrayed on the circuit breaker-side terminal block to positionally cooperate with the female terminal housings when the cassette-side terminal block is in the service position and when the rack-in operation is at least in the test position and/or the connected position.
