Why Choose the IMO B6CR1N20-30-A RCBO?
The IMO B6CR1N20-30-A is a high-performance Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide comprehensive protection against earth leakage, overload and short circuit faults in residential, commercial and industrial electrical installations. Manufactured to IEC 61009, it combines the functions of an MCB and RCD into a single compact device for simplified installation and enhanced circuit protection.
Part of the reliable IMO B6 RCBO range, this device features a Type A residual current protection, enabling it to detect both AC and pulsating DC residual currents commonly generated by modern electronic equipment. Its compact single-module design saves valuable DIN rail space while delivering dependable protection for individual circuits.
Rated at 20 A with a 30 mA residual operating current, a Type C tripping characteristic and a 6 kA short-circuit breaking capacity, the B6CR1N20-30-A is ideal for protecting circuits supplying lighting, socket outlets, commercial equipment and inductive loads where moderate inrush currents are expected.

Reliable Electrical Circuit Protection
The IMO B6CR1N20-30-A continuously monitors electrical circuits for overloads, short circuits and earth leakage faults. If a fault is detected, the RCBO disconnects the supply rapidly, helping to protect personnel from electric shock whilst reducing the risk of equipment damage and electrical fires.
Its Type A residual current sensing makes it particularly suitable for installations containing modern electronic equipment, including appliances with switched-mode power supplies, LED lighting and variable speed devices that may generate pulsating DC leakage currents.

- Commercial electrical distribution boards.
- Industrial control panels.
- Residential consumer units.
- Lighting circuits.
- Socket outlet protection.
- Small motors and inductive loads.
- Building services installations.
- General electrical installations.
