2 IMPULSE OUTPUT FOR TRIPPING COIL
The Low Energy tripping coil of the circuit breaker (CB) can be interfaced on relay terminal block. The
trip energy (12-24 V DC <= 0.1J) is provided by a capacitor in the relay. The capacitors are charged
by a current input or the auxiliary voltage .The length of the trip impulse is 50 ms (if the output is not
burdened). The pause between the individual pulses depends on the impedance of the tripping coil
and the current level. The pulse lasts as long as the activation threshold is exceeded. The voltage
level of the energy output depends on the discharging time.
