Dear all,
is ther any body who can tell me about the
setting of ACB(air circuit breaker ). what kind of it,s
setting is and how to do it,s setting. also please tell me
the setting of VCB(vaccume circuit breaker) . please tell
me their setting,s.
i will b very thank ful to all of u.
Thank,s and Regard,s.

Dear Mohammed,
1.MCB for normal commercial & household purpose and it's
having seperate cuurent transformer.
2.ACB is used in LT panel, which is protective device for
entire LT panel and it having current transformer.based on
ratting of CT, ACB tripping the supply voltage anf it's
having seperate current selector range.
3.VCB is used in I/p way or O/P of 11KV,22KV,33KV
transformers and it's operation is same for ACB
4.SF-6 is used in 110 KV and above and it's operation is
same as the VCB

I am an American living in Vietnam and I have recently gotten a refrigerator from Japan and it is rated for 100 vac, but the power here is 220 so I bought a voltage stabilizer it has a 1 kva output rating. Can you please tell me what the amperage is? I'm confused and without a working fridge.
