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 currents and voltages.

MCB is designed for low voltage applications, typically up to 1000V, while MCCB is designed for higher currents and voltages, typically up to 2500V.
MCB is usually thermal-magnetic in operation, while MCCB can be thermal-magnetic or electronic trip units.
MCB is compact in size and has fixed trip settings, while MCCB is larger and has adjustable trip settings.
Examples: MCBs are commonly used in residential and commercial buildings for circuit protection, while MCCBs are used in industrial applications for higher power distribution.
