Abstract
A multi-phase circuit breaker assembly,includes 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 has a plurality of line wiring terminals,at a first end,of the housing. Each line wiring terminal corresponds to a phase of the circuit breaker. A terminal cover,is removably coupled to the first end of the housing so as to cover the line wiring terminals and prevent access to the line wiring terminals when coupled to the first end of the housing, and to gain access to the line wiring terminals only when removed from the first end of the housing. The terminal cover,includes a plurality of vent structures,integrally formed therewith. Each vent structure is in communication with an associated gas venting chamber and each vent structure is 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 a different phase, and 2) from coming into contact with wiring terminals of the same phase, thereby preventing a short circuit.
