The CTD-1 manufactured by Electromagnetic Industries is designed to provide a source of energy for a circuit breaker or switch to trip during a loss of normal AC or DC power.
These devices are protected against inadvertent short circuits, input from line surges and inductive kickback from trip coils. The nominal 120Volts AC or 125 DC is applied between “AC” and ‘COM” terminals. This voltage is half wave rectified and applied across the trip capacitor to give the output trip voltage. The charge stored in the capacitor (330 uF @168 VDC) is available between “+” and “COM” terminals for the trip coil operation. The half wave rectification circuitry provides the advantage of maintaining a common neutral connection from the input and output while still maintaining the charge in the trip capacitor after a loss of control power.
The capacitor is continuously charged when control power is applied. This provides energy for normal trip coil operation. Because mechanical relays are not used, energy from the trip coil operation is immediately available with the loss of control power. When the control power returns, the capacitor will recharge and will be able to supply energy for the next trip coil operation.
