What is the difference between MCB and MCCB?

Question

Accepted Answer

MCB is a miniature circuit breaker used for low voltage applications, while MCCB is a molded case circuit breaker used for higher voltage applications.

MCB is designed for low voltage applications, typically up to 1000V, while MCCB is designed for higher voltage applications, typically up to 10000V.
MCB is usually rated up to 125A, while MCCB can be rated higher, up to 2500A or more.
MCB is more compact in size and used for residential or light commercial applications, while MCCB is larger and used in industrial settings.
MCB is more sensitive to overcurrents and trips faster than MCCB in case of a fault.
Examples: A Schneider Electric Easy9 MCB is used in a residential electrical panel, while a Siemens Sentron MCCB is used in an industrial power distribution system.
