Patent ID: 8717731

Claim:
An apparatus, comprising: a controlled circuit breaker configured to input and output current generated by a first voltage phase, and further comprising a control mechanism operably coupled to a first pair of separable contacts and configured to selectively open the first pair of separable contacts to interrupt the current generated by the first voltage phase in response to a control signal; an uncontrolled circuit breaker configured to input and output current generated by a second voltage phase that is different than the first voltage phase, and further comprising a trip mechanism configured to selectively open a second pair of separable contacts to interrupt the current generated by the second voltage phase in response to an overload event; and where the controlled circuit breaker and the uncontrolled circuit breaker are mechanically connected to one another in fixed relative positions such that when the apparatus is installed in a circuit breaker panel, the controlled circuit breaker and the uncontrolled circuit breaker are installed in adjacent slots.
