MCB, Miniature Circuit Breaker in UAE

MCB, Miniature Circuit Breaker

An MCB is a type of electrical switch that operates automatically. Miniature circuit breakers are designed to protect an electrical circuit from harm caused by excessive current. To protect against electrical failures and equipment failure, they are designed to trip upon an overload or short circuit.

The purpose of ABB's miniature circuit breakers (MCBs) is to guard against overloads and short circuits that could harm electrical circuits. To avoid possible risks, they immediately cut the electrical circuit under unusual circumstances.

Important attributes:

High Reliability: ABB MCBs are renowned for their longevity and reliable operation.
Safety: Made to keep electrical installations safe by guarding against short circuits and overloads.
Broad Range: To accommodate diverse applications, it is offered in a variety of types and ratings.
Simple Installation: DIN rails can be quickly and easily installed thanks to the modular architecture.
