whats the diff b/w mpcb and mcb?weather it trips on single
phasing or not.
Answer Posted / atul
The question is still not clear to me......
as.
1). MCB protects from overloadin,short circuit..
2). MPCB protects from overloading,short circuit and motor disconection...in all of the above cases it will trip....nd moreover the main dfrnc btwn mcb nd mpcb is dat mpcb is provided with auxiliary cntacts(normally open nd normally closed)basically mpcb is connected with cntactors to provide two cmponent starting.......nd mpcb ranges r variable it can be set from frnt bt mcb is set for a fixed rating....
