Capacitor trip unit 601D1200
CAPACITOR TRIP UNIT 601D1200
This unit has been designed to provide energy for tripping of the circuit breaker.
The unit has a 66 µF capacitor which is kept charged to 300Vdc by the AC supply voltage. In the case of an arcing fault the AC voltage will disappear and the energy stored in the capacitor can be used for tripping of the circuit breaker.
The unit has 2 green indicating LED’s, one is for indicating that AC voltage is present, the other indicates that the capacitor is charged with DC voltage.
The unit can also be used to increase the stored energy of an AC Arc D-tect relay 601D0900 if several or extremely large circuit breakers are to be tripped.
The unit is available with 132 µF storage capacitor as well. The number is then 601D1200-01.
CAUTION:
Dangerous voltage is present at the storage capacitor even after the unit has been disconnected from the mains. The unit has a self-discharge circuit which will reduce the voltage.
to a safe level within 2 minutes after disconnection from the mains.
