how to select a breaker (MCB,MCCB,ELCB) for 18.5 kw, 3 ph.
480 v, 60 hz induction motor?
Answer Posted / engr ali mehmood
MCB are used for small power application; usually used in
the household appliances current rating is 5A.
MCCB are used in high power application in generation
station above 100A;Rarely used but the most common used in
industries is MPCB variable Rating of current adjust
according to the load current of the the appliances. and
the ELCB is a earth leakige circuit breaker it is use for a
body earth ground earth
