During discharge of a storage battery the pointer of the ampere hour metermoves from the zero position of the scale in a clockwise direction toward the fullscale reading, hut when the battery is placed on charge the pointer moves m acounter-clockwise direction toward the zero division of the scale When ithas reached this point, the contacts A and B Fig. 85 are closed and the circuitbreaker is tripped by the no voltage release magnet M. This cuts off the charg-ing current. Current flows through winding M only during the time requiredto throw the breaker, the current being turned off automatically, through a setof contacts, by the breaker armature. The circuit for the no-voltage releasemagnet is closed when the circuit breaker proper is set by hand.
