51,601 ABSTRACT OF THE DISCLOSURE A molded case circuit breaker includes a solenoid control circuit for controllably energizing a solenoid to actuate a motor operator to automat- ically move a handle of the circuit breaker to change the operative condition of the circuit breaker. The control circuit includes a monostable multivibrator that supplies an electrical pulse to the solenoid upon the receipt of a switching initiation signal. The time duration of the electrical pulse is control- led to be sufficiently long to assure proper opera- tion of the solenoid and is determined by a timing circuit coupled to the source of operating voltage for the solenoid. If the operating voltage de- creases, the time required to charge the timing cir- cuit increases, increasing the duration of the elec- trical pulse of the solenoid to assure proper opera- tion under low voltage conditions.
