Yes there is a shut coil in every ACB. You will find both end of this coil at ACB terminals X1 and X2. When you give appropriate supply to this shunt coil ACB will trip. This shunt coil is give for remote trip maually or by any other supervisory relay
When there is voltage the coil generates magnetic field which attracts spindel and spring ( see at 7:40) in which spindel fixed it get charged. It keep in this position when voltage fails this spring releases stored energy and spindel strikes on a mechanical point and it trips ACB and it keep press that mechanical point which keeps ACB in trip position now if we removes UV coil there is nothing to press or keep in press position to trip ACB or remain it in same... so by removing this coil ACB is free from UV trip
U can identity it easily as UV coil is only one where spindel comes inside of coil when u give voltage to coil . Remaining two spindel will go out of coil when u give voltage to coil

Thanks
Hello, nice video!! I want to ask you if it is possible and how we take out and make maintenance at fixed mounted installation of this ACB?
ACB repair aur service pr video bnaye

How to check the trip unit function wether it is healthy
@@santhoshrodrigues2791 there are several test kits available in market for testing tripping unit functioning example- EATON fuction test kit
Hello sir in Siemens ACB shunt trip which auxiliary switch NO going to use for status S24 or any other function
Brother iske control circuit ka baare ma bhi bataao
VERY NICE THANKS FOR SHARING
WL II 2000 N ACB what is stand for N
Sir please confirm whether 3WA test and service connection switch is same as 3WL
Plz tell about it in details
SIR WHEN YOU REMOVED UNDER VOLTAGE THEN HOW IT WAS ABLE TO CLOSE ? HOW YOU DEFEATED THE UNDER VOLTAGE FUNCTION ? OK
When there is voltage the coil generates magnetic field which attracts spindel and spring ( see at 7:40) in which spindel fixed it get charged. It keep in this position when voltage fails this spring releases stored energy and spindel strikes on a mechanical point and it trips ACB and it keep press that mechanical point which keeps ACB in trip position now if we removes UV coil there is nothing to press or keep in press position to trip ACB or remain it in same... so by removing this coil ACB is free from UV trip
Very good
Can you show me how to remove complete mechanism
sir how to know which relay is UV
U can identity it easily as UV coil is only one where spindel comes inside of coil when u give voltage to coil . Remaining two spindel will go out of coil when u give voltage to coil
Plz Relay setting and control wiring ke baare me diagram dekar batao
I am test a WLH3A340 CAN YOU HELP ME
HELLO DINESH. SORRY, YOUR DEMONSTRATION IS UNSATISFACTORY.
Hindi plz
Sir please give some more details.
