Why Choose the IMO B6CRC1N25-30 RCBO?
The IMO B6CRC1N25-30 is a compact and dependable Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to protect single-phase electrical circuits against earth leakage, overload and short-circuit faults. Combining the functions of an MCB and an RCD within one device, it provides comprehensive circuit protection while reducing the amount of DIN rail space required inside a consumer unit or distribution board.
Part of the IMO B6 circuit protection range, this RCBO is suitable for residential, commercial and light industrial electrical installations. Its C curve operating characteristic allows it to accommodate moderate starting currents from equipment such as small motors, fluorescent lighting, transformers and inductive loads while still providing reliable protection during fault conditions.
With a rated current of 25 A, a 30 mA residual operating current and a 230 V AC single-phase supply, the B6CRC1N25-30 is ideal for protecting dedicated socket circuits, fixed appliances, heating equipment and other final circuits. Its compact 1P+N construction enables straightforward installation on a standard 35 mm DIN rail.
Key Advantages
- Combined residual current and overcurrent protection in one device.
- 25 A rated current for residential and commercial final circuits.
- C curve tripping characteristic suitable for moderate inrush currents.
- 30 mA earth leakage sensitivity for additional personal protection.
- 6 kA short-circuit breaking capacity.
- Compact DIN rail design helps conserve distribution board space.

Combined Protection for Electrical Circuits
The IMO B6CRC1N25-30 monitors current flowing through the protected circuit and rapidly disconnects the supply when an overload, short circuit or residual current fault is detected. This combined protection helps reduce the risk of electric shock, damaged wiring, electrical fires and equipment failure.
By incorporating residual current and overcurrent protection into one compact unit, the RCBO allows individual circuits to be isolated without unnecessarily disconnecting unrelated circuits. This can improve fault identification, system availability and maintenance efficiency within modern electrical installations.
Typical Applications
- Residential consumer units.
- Commercial distribution boards.
- Socket outlet circuits.
- Fixed electrical appliances.
- Electric heating circuits.
- Lighting and building services systems.
- Light industrial control panels.
