The aforementioned types of Circuit Breakers are used in LV System and generally based on the same operating principle.
\nMCB and MCCB\/ICCB have a bimetal heater for overload which releases the Contact s while for short circuit the trip \/ electromagnet hammers itself against moving contacts. The arc created by breaking contacts is extinguished in an arc chamber. Are defined as \u201cThermo-magnetic \u201c CBs , accordingly. It is operating characteristic addressing the overload by thermal action of the bimetal strip and instantaneously dealing with short circuit occurrences by electromagnetic action. <\/p>\n
MCB \u2013 Miniature Circuit Breaker is suitable for domestic usage. Used to protect final circuits from O\/C such as Overload & Short Circuit.

\nType B is suitable in domestic premises.
\nType C is used in commercial & industrial applications.
\nType D is suitable for application where a high in-rush current is expected.
\nii- MCB is of low breaking \/ making capacity as well as low current rating compared with MCCB\/ICCB. MCBs available in different number of poles (SP, DP, TP,,). <\/p>\n
MCCB \u2013 Molded Case Circuit Breaker & Insulated Case Circuit breaker are also current limiting devices but with high making\/ breaking capacity and current ratings compared with MCB.
