What is an MCB?

A Miniature Circuit Breaker (MCB) is an electrical device which automatically protects your electrical circuits from overcurrent. They are a type of switch, and they work by instantly turning off electrical circuits when they detect irregular conditions, such as excess current. This helps to guard against equipment failure or electrical faults.

These circuit-breaking components are commonly used in many kinds of commercial, industrial, and domestic applications. They are more reliable than fuses, are resettable unlike fuses, and are more sensitive. You can choose from a number of different types available: A, B, C, D, K and Z. These MCB types have different tripping characteristics, also called the 'trip curve'.

Eaton's offer includes popular series and ranges such as MEMshield, xEffect, Faz, and xPole. They come with features and benefits such as clear contact position indication, up to 4 poles, thermal/magnetic overcurrent protection, screw terminals, resilient housing to withstand tough conditions, a wide variety of current ratings, long mechanical lifespans, and finger-safe ratings. Many of their MCBs can be mounted via DIN rail, for easy set-up.
