Why Choose the IMO B6CR1N40-30-A RCBO?
The IMO B6CR1N40-30-A is a compact and dependable Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to protect electrical circuits against earth leakage, overload and short-circuit faults. By combining residual current and overcurrent protection within one device, it helps simplify installation and reduce the amount of space required inside consumer units, distribution boards and electrical control panels.
As part of the established IMO B6 RCBO range, this model provides Type A residual current protection. It can detect sinusoidal AC and pulsating DC residual currents, making it suitable for modern installations containing electronic appliances, LED drivers, switched-mode power supplies and other equipment incorporating semiconductor components.
With a rated current of 40 A, a residual operating current of 30 mA and a Type C tripping characteristic, the B6CR1N40-30-A is suitable for higher-load final circuits and equipment that may produce moderate starting currents. Its DIN rail mounting format enables straightforward installation in residential, commercial and light industrial electrical systems.

Reliable Protection for Modern Electrical Circuits
The IMO B6CR1N40-30-A continuously monitors the connected circuit for excessive current and current leaking to earth. When a qualifying overload, short circuit or residual current fault occurs, the RCBO rapidly disconnects the electrical supply to help reduce the risk of electric shock, damaged equipment and electrical fires.
Type A residual current protection is particularly useful in contemporary installations because many electronic devices can produce pulsating DC leakage currents. The Type C operating characteristic also enables the RCBO to accommodate the moderate inrush currents associated with pumps, transformers, lighting systems and small motors.
Typical Applications
- Residential consumer units.
- Commercial distribution boards.
- Higher-load socket outlet circuits.
- Lighting and LED installations.
- Small motors and pumps.
- Electronic equipment circuits.
- Building services installations.
- Industrial and OEM control panels.
