UV IS Under voltage realease type relay,
uv is installed in breaker and it is designed so that when
the supply of its coil is interupted it opens the breaker.
when you give supply then only you can close the breaker.
it is installed manily for interlocking.
we can use them in almost all type of onload ckt breaker
like-- MCCB,ACB,VCB,SF6 Etc...
