B6CR1N16-30 IMO RCBO 10kA, 30mA, C Curve 1 Pole + N, 16Amp, 230VAC
£61.00
Why Choose the IMO B6CR1N16-30 RCBO?
The IMO B6CR1N16-30 is a compact residual current circuit breaker with overcurrent protection designed to protect compatible single-phase electrical circuits against earth leakage, overloads and short circuits. Combining MCB and RCD functions within one device helps simplify distribution-board layouts while providing comprehensive protection for wiring, equipment and users.
This model has a C curve tripping characteristic, making it suitable for circuits with moderate inrush currents from equipment such as contactors, transformers, small motors and power supplies. As the ordering code has no Type A suffix, it has a Type AC residual-current characteristic for detecting alternating sinusoidal residual currents.
Featuring a 16 A rated current, 30 mA residual operating current and 6 kA short-circuit capacity, the B6CR1N16-30 provides compact circuit protection for commercial, industrial and OEM electrical installations.
Key Advantages
- Combines earth leakage, overload and short-circuit protection.
- C curve characteristic accommodates moderate equipment-starting currents.
- 16 A rated current for general-purpose final circuits.
- 30 mA sensitivity provides additional protection against electric shock.
- 6 kA short-circuit capacity supports dependable fault interruption.
- Compact 18 mm single-module construction saves panel space.
- Finger-protected terminals support safer installation and maintenance.

Combined Protection for Electrical Final Circuits
The IMO B6CR1N16-30 monitors load current and residual leakage current within the protected circuit. It disconnects the supply when an overload, short circuit or qualifying earth leakage fault occurs, helping safeguard electrical cabling, connected equipment and personnel.
Its C curve characteristic provides tolerance for normal starting surges while maintaining overcurrent protection. This makes the RCBO suitable for circuits supplying equipment with moderate inrush currents that could cause unnecessary operation of a more sensitive B curve device.
The Type AC characteristic is intended for circuits where the expected residual fault current is alternating and sinusoidal. Where equipment may generate pulsating DC residual currents, a compatible Type A RCBO should be considered instead.
Typical Applications
- Industrial control panels.
- Commercial distribution boards.
- Machine-control circuits.
- General lighting circuits.
- Contactors and control transformers.
- Small motors and inductive loads.
- OEM machinery and electrical equipment.
- Building-services installations.
