What is MCB miniature circuit breaker?

MCB or miniature circuit breaker is an electromechanical device that can protect circuits from overcurrent effects. Overcurrent in a circuit may be caused by short circuits, overloads, or incorrect design.

In short, MCB is a device used for overload and short circuit protection. They are used in residential and commercial areas. Just as we spend time thoroughly inspecting equipment such as washing machines or refrigerators before purchasing, we must also study miniature circuit breakers.

MCB is a better alternative to fuses because once overload is detected, it does not need to be replaced. Unlike fuses, MCBs are easy to operate, thus improving operational safety and convenience without incurring high operating costs. They are used to protect circuits with lower currents and have the following important parameters:

Current rated value - Ampere

Short circuit rating - kiloampere (kA)

Working characteristics - B, C, D, Z or K curves

Do not confuse miniature circuit breakers with MCCBs (molded case circuit breakers) or GFCI (ground fault circuit breakers).
