The WRT106C-030 is a 6A C Curve Type A RCBO combining residual current and overcurrent protection in one compact device. With switched live and neutral disconnection for full isolation, bi-directional wiring for use in solar PV and inverter-fed systems, and high immunity electronics to reduce nuisance trips, it is built for EV chargers, motors, and circuits with high inrush loads.
Designed to detect both AC faults and pulsating DC leakage, this RCBO ensures compliance with the 18th Edition Wiring Regulations (Amendment 2) and fits standard 18mm DIN rail consumer units.
Installer Tip: The C Curve is recommended for circuits with high inrush current such as EV charge points, motors, and heat pumps. For domestic lighting and socket circuits, the B Curve version is more suitable.
Key Features
- 6A C Curve Type A RCBO – overload + 30mA earth leakage protection
- Switched live & neutral – disconnects both conductors
- High immunity design – resists nuisance tripping from harmonics
- Bi-directional wiring – suitable for solar and inverter-fed systems
- Compact 18mm module – fits consumer units easily
- 10kA breaking capacity – suitable for residential and light commercial use
- Tested to IEC/EN 61009-1

Why choose a C Curve RCBO?
C Curve RCBOs are designed for circuits with high inrush currents, such as EV chargers, motors, and heat pumps. They prevent false trips on startup compared to B Curve models.
Is this suitable for solar PV?
Yes – its bi-directional wiring makes it suitable for inverter-fed solar systems.
Does it fully isolate the circuit?
Yes – switched live and neutral ensure safe disconnection of both conductors.
What’s the benefit of high immunity?
It reduces nuisance tripping caused by harmonics, switching surges, or transient voltages in inverter-heavy environments.
