Abstract
A circuit breaker includes a housing, line and load terminals, first and second circuit breaker mechanisms, an operating handle having on and off positions, and first and second links from the operating handle to the respective first and second operating mechanisms. Each of the circuit breaker mechanisms includes a set of separable contacts in series with the other separable contacts between the line and load terminals, an operating mechanism for moving the corresponding separable contacts between open and closed positions, and a trip mechanism cooperating with the corresponding operating mechanism for moving the corresponding separable contacts from the closed to the open position thereof. The first and second links engage the first and second operating mechanisms to move the first and second separable contacts, respectively, between the corresponding closed and open positions thereof responsive to the on and off positions, respectively, of the operating handle.
