What is MCB?

MCB most commonly refers to a Miniature Circuit Breaker. It is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow to prevent damage to equipment and reduce the risk of fire. They are commonly used in residential, commercial, and industrial electrical distribution systems.

MCB Competitor Technologies

RCCB

No summary available

RCCBs (Residual Current Circuit Breakers) provide protection against earth leakage faults, which MCBs do not. While MCBs protect against overcurrent and short circuits, RCCBs offer a different protection mechanism, acting as a competitor in overall circuit protection, although they often work together.

MCCB

MCCBs (Molded Case Circuit Breakers) are similar to MCBs in function (overcurrent and short circuit protection) but are used for higher current ratings and breaking capacities. Thus, they directly compete with MCBs, especially in industrial and commercial applications.

ACB

ACBs (Air Circuit Breakers) are used for very high current and voltage applications, typically serving as main incoming circuit breakers. They perform a similar function to MCBs, but at a much larger scale, making them competitors in high-power applications.

MCB Complementary Technologies

contactors

Contactors are electrically controlled switches used to switch a power circuit, frequently used to control motors or other high-power loads. MCBs often protect the circuit that the contactor switches, therefore they are complementary.
