ac , is applied between the ’AC ’ and ’ COM ’ terminals.
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 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.
