Abstract:
A multi-phase circuit breaker assembly comprising:a circuit breaker having a housing containing circuit breaker operating components and having a gas venting chamber associated with each phase of the circuit breaker; the circuit breaker having a plurality of line wiring terminals at a first end of said housing, each line wiring terminal corresponding to a phase of the circuit breaker; anda terminal cover removably coupled to said first end of said housing so as to cover said line wiring terminals and prevent access to said line wiring terminals when coupled to said first end of said housing, and to gain access to said line wiring terminals only when removed from said first end of said housing, said terminal cover including a plurality of vent structures integrally formed therewith, each vent structure being in communication with an associated gas venting chamber and each vent structure being isolated from each other such that arc gases generated in each phase of the circuit breaker are exhausted through an associated vent structure with arc gases from one phase being prevented 1) from coming into contact with arc gases or line wiring terminals of different phases, and 2) from coming into contact with a line wiring terminal of the same phase, thereby preventing a short circuit.
