What is the difference between MCB & MCCB,
Where it can be used,
Answer Posted / balakrishnan
MCB is normally used for small loads like in DBs, MCB can
only protect loads from over current, it is available upto
100A.
MCCB is having some special characteristics over MCB. It
protects loads from over current, short circuit current and
earth fault protection. Moreover it is available in all
ranges (16A to 3200A).
MCBs are used mostly in DBs, MCCBs are used for all SMDBs
and MDBs.

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
