摘要
A circuit breaker arraignment includes at least two trip mechanisms. The first trip mechanism acts to immediately trip to open contacts of the circuit breaker upon reaching a first threshold current level, and the second trip mechanism acts to trip to open the contacts once both a second current threshold is reached and a time delay has elapsed. The contacts are moved by a linkage assembly that is held under mechanical advantage such that when acted on by one of the two trip mechanisms, the mechanical advantage is released to rapidly open the contacts.
