the trip capacitor, giving an output trip voltage. The charge stored in these capacitors is available between the ‘+’ and “ COMMON ” 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 .
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.
Capacitor Trip Device
Model CTD
APPLICATION:
Provides a source of
energy for circuit breaker
and switch trip coil
operation during a loss
of AC control voltage.
Nominal 120 Volts ac , or 240 Volts ac is is applied between the “ INPUT ” and “ COMMON ” terminals. This voltage is half wave rectif ied and applied across
The capacitor is continuously charged when control power is available, providing energy for normal trip coil operation. Because mechanical relays are not
These devices are protected against inadvertent output short circuit , inductive kickback from the trip coil, and input line voltage surges.
