Where it can be used,
Answer Posted / abhishek tiwari
MCB (Miniature Circuit Breaker)—rated current not more than
100 A. Trip characteristics normally not adjustable.
Thermal or thermal-magnetic operation.
MCCB (Molded Case Circuit Breaker)—rated current up to 2500
A. Thermal or thermal-magnetic operation. Trip current may
be adjustable in larger ratings.
