ABSTRACT:
A mechanism for a circuit breaker contact arm that allows current limiting by reducing the opening time is disclosed. A secondary trip assembly is arranged to actuate due to magnetic forces generated during an undesirable electrical condition such as a short circuit. The secondary trip system releases a contact arm assembly allowing the contact arm to rotate to an open position that interrupts the flow of electrical power.
