The IMO B6BRC1N25-30 is a compact Residual Current Circuit Breaker with Overcurrent Protection (RCBO) that combines overload, short-circuit and earth leakage protection within a single device. Designed by IMO Precision Controls, it provides dependable protection for commercial, industrial and OEM electrical installations while reducing the number of protective devices required in a distribution board.
By integrating the functions of both a miniature circuit breaker (MCB) and a residual current device (RCD), the B6BRC1N25-30 helps simplify panel layouts while maintaining a high level of electrical safety. Its compact DIN rail design allows quick installation into new or existing electrical systems.
With a 25 A rated current, B curve tripping characteristic, 30 mA residual current sensitivity and 6 kA breaking capacity, this RCBO is ideal for protecting final circuits supplying industrial machinery, commercial equipment and electrical distribution systems.
