What is the difference between MCCB,ELCB,RCB & MCB

Answer Posted / h s sandhu

Although the answer for MCCB and ELCB is all right but mcb stands for Miniature Ckt breaker and is used in domestic and industrial area with low fault level and with B,C and D curve application for Light/resistance,Inductive load and Non linear loads of PCs etc which causes lot of harmonics in the supply line. .The protec for MCCB is more and of higher level than MCB.RCB is similar to ELCB which checks the leakage current.
