Charging motors became popular for use in Air circuit breakers around 1960. Circuit breaker charging motors allowed closing springs to charge (compress) prior to closing the contacts, which allowed breakers to become stored energy type breakers – which means they could close faster.
Circuit breakers motors are universal, but come in several different voltages: 120VAC,/125VDC, 230VAC/250VDC and 48VDC.
You must have the correct voltage for your switchgear system, and have the correct charging motor model for the circuit breaker model that you have. Different generations of circuit breakers have different style motors, so it is important when ordering the correct charging motor to specify breaker type and circuit breaker closing voltage.
