B6CR1N20-30 IMO RCBO 10kA, 30mA, C Curve 1 Pole + N, 20Amp, 230VAC
£61.00
Why Choose the IMO B6CR1N20-30 RCBO?
The IMO B6CR1N20-30 is a compact Residual Current Circuit Breaker with Overcurrent Protection (RCBO) that combines overload, short-circuit and earth leakage protection in a single DIN rail-mounted device. It integrates the functions of both an MCB and an RCD, helping simplify distribution board layouts while providing reliable protection for electrical installations.
This model features a C Curve tripping characteristic, making it ideal for circuits with moderate inrush currents such as motors, transformers, contactors and inductive loads. As this model does not carry the -A suffix, it provides Type AC residual-current protection, designed to detect alternating sinusoidal earth leakage currents.
With a 20 A rated current, 30 mA residual-current sensitivity, 6 kA short-circuit breaking capacity and compact 1 Pole + Neutral construction, the B6CR1N20-30 is well suited to commercial, industrial and OEM electrical installations.
Key Advantages
- Combines overload, short-circuit and earth leakage protection in one compact device.
- C Curve characteristic accommodates moderate starting currents.
- 20 A rated current for higher-capacity final circuits.
- 30 mA residual-current sensitivity provides additional protection against electric shock.
- Type AC residual-current protection.
- 6 kA short-circuit breaking capacity.
- Compact 18 mm single-module DIN rail design.
- Compatible with IMO MCB accessories.

Reliable Protection for Commercial & Industrial Circuits
The IMO B6CR1N20-30 continuously monitors both load current and residual leakage current. If an overload, short circuit or earth fault occurs, the RCBO disconnects the supply rapidly to help protect electrical wiring, connected equipment and personnel.
Its C Curve characteristic provides excellent tolerance to the normal inrush currents generated by transformers, contactors, power supplies and other inductive equipment while maintaining dependable overcurrent protection. The Type AC residual-current characteristic is intended for circuits where only alternating sinusoidal residual currents are expected.
Typical Applications
- Commercial distribution boards.
- Industrial control panels.
- Machine control circuits.
- Lighting installations.
- General-purpose socket circuits.
- OEM electrical equipment.
- Automation systems.
- Building services installations.
