Nominal 120 Volts ac ,or 125 Volts dc is applied between the ’AC ’ and ’ COM ’ term inals. This voltage is half wave rectif ied and applied across the trip capacitor,
giving an output trip voltage. The charge stored in this capacitor (330 uF or 1500 uF) is available between the ‘+’ and ’COM ’ terminals for breaker trip coil
operation. The half wave rectif ication circuitry provides the advantage of maintaining a common neutral connection from input while still maintaining the
charge in the the trip capacitor after control power is lost .
The capacitor is continuously charged when control power is available, providing energy for normal trip coil operation. Because mechanical relays are not
involved, energy for the trip coil operation is immediately available with the loss of control power. When the control power returns, the capacitor automatically
charges to supply energy for the next trip coil.
