Why Choose the IMO B6BR1N40-30 RCBO?
The IMO B6BR1N40-30 is a compact Residual Current Circuit Breaker with Overcurrent Protection (RCBO) engineered to provide reliable protection against earth leakage, overload and short-circuit faults in single-phase electrical installations. By combining the functions of an RCCB and MCB into a single device, it simplifies distribution board layouts whilst delivering dependable circuit protection.
With a 40 A rated current, 30 mA residual operating current, Type AC residual current protection and a B curve tripping characteristic, the B6BR1N40-30 is ideal for protecting higher-load circuits in commercial, residential and light industrial applications where fast fault detection and reliable isolation are essential.
Manufactured in accordance with IEC 61009-1, the device features a 1 Pole + Neutral (1P+N) configuration, a 6 kA short-circuit breaking capacity, compact DIN rail mounting and an integrated test button for routine verification of residual current protection.
Key Advantages
- Provides combined earth leakage, overload and short-circuit protection.
- 40 A rated current suitable for higher-load single-phase circuits.
- 30 mA residual sensitivity helps provide additional protection against electric shock.
- Type AC residual current protection for alternating sinusoidal leakage currents.
- B curve tripping characteristic for circuits with relatively low inrush currents.
- Compact DIN rail mounted design helps maximise available enclosure space.

Comprehensive Circuit Protection
The IMO B6BR1N40-30 continuously monitors electrical circuits for overload conditions, short circuits and residual current leakage. Should a fault occur, the RCBO disconnects the circuit rapidly to help protect personnel, wiring and connected electrical equipment.
Its B curve operating characteristic makes it particularly suitable for general-purpose electrical circuits with relatively low inrush currents. The integrated RCBO design also simplifies installation by combining multiple protective functions into a single compact device.

- Commercial distribution boards.
- Residential consumer units.
- Socket outlet circuits.
- Electric heating circuits.
- Industrial control panels.
- OEM machinery and automation equipment.
