An automatic circuit breaker for an electrical storage battery is adapted to be mounted on a battery terminal post so that the battery post forms one contact of the circuit breaker. A latch mechanism holds a contact piston against the battery post to form the main contacts of the breaker, and a solenoid trip mechanism disengages the latch mechanism when energized by a condition responsive switch. An auxiliary switch is provided to be held open by the latch mechanism when the latch mechanism releases the contact piston to open the main contacts of the circuit breaker.
