Abstract
A power distribution unit includes a two pole circuit breaker having a first pole electrically coupled to an x-phase circuit portion of the power distribution unit and having a second pole electrically coupled to a y-phase circuit portion of the power distribution unit. The two pole circuit breaker is so designed that both of the two poles of the circuit breaker trip simultaneously and open even when an undesired electrical condition exists on the portion of the power distribution unit electrically coupled to only one of the poles.
Claims22
A system for electrically coupling with an electrical power source having a first phase line and a second phase line, the system comprising:
- a two pole circuit breaker having a first input terminal, a second input terminal, a first output terminal, and a second output terminal,
