Single mcb breaker

The Single MCB Breaker is the most common circuit protection device found in residential and commercial distribution boards. It protects a single circuit — such as a lighting ring, socket ring, or dedicated appliance feed — by automatically tripping when it detects overcurrent or a short-circuit fault. Available in multiple current ratings (6A, 10A, 16A, 20A, 32A, etc.) to match different circuit requirements, it mounts on a standard DIN rail and takes up just one module width in the board. The toggle handle provides clear on/off indication and allows manual isolation when maintenance is needed. An essential building block of every electrical distribution system.
