The IMO B6CR1N25-100-A is a high-performance Residual Current Circuit Breaker with Overcurrent Protection (RCBO) engineered to provide reliable protection against earth leakage, overload and short circuit faults in commercial, industrial and residential electrical installations. Combining the functionality of an MCB and RCD within a single compact device, it simplifies installation while delivering dependable circuit protection in accordance with IEC 61009.
Part of the trusted IMO B6 RCBO range, this model incorporates Type A residual current protection, allowing it to detect both AC and pulsating DC residual currents commonly produced by modern electronic equipment. Its slim DIN rail mounted design helps maximise valuable panel space whilst maintaining high levels of electrical safety and operational reliability.
With a 25 A rated current, 100 mA residual operating current, Type C tripping characteristic and a 10 kA short-circuit breaking capacity, the B6CR1N25-100-A is well suited for protecting distribution circuits, machinery, control panels and industrial electrical systems requiring dependable fault protection.

Reliable Protection for Modern Electrical Systems
The IMO B6CR1N25-100-A continuously monitors circuits for earth leakage, overload and short circuit conditions. If a fault is detected, the RCBO disconnects the electrical supply rapidly, helping protect people, equipment and installations whilst reducing the risk of electrical fires and costly downtime.
Its Type A residual current sensing makes it particularly suitable for installations containing variable speed drives, LED lighting, switched-mode power supplies and other electronic equipment that may generate pulsating DC leakage currents.
