The IMO B6BRC1N20-30 is a compact RCBO (Residual Current Circuit Breaker with Overcurrent Protection) that combines overload, short-circuit and earth leakage protection in a single device. Manufactured by IMO Precision Controls, it is designed for commercial, industrial and OEM electrical installations where reliable circuit protection and efficient panel design are essential.
By integrating the functions of both a miniature circuit breaker (MCB) and a residual current device (RCD), the B6BRC1N20-30 reduces installation space while providing comprehensive protection for electrical circuits. Its compact DIN rail design enables quick installation within distribution boards and control panels.
Featuring a 20 A current rating, B curve trip characteristic, 30 mA residual current sensitivity and 6 kA breaking capacity, this RCBO is suitable for protecting final circuits supplying industrial machinery, commercial equipment and building services.
