The WRB132C-030 High Immunity Type A Mini RCBO is a 32A C Curve protective device engineered for circuits with higher inrush demands. Its slim 18mm design combines overload, short-circuit, and residual current protection in one module. With 30mA Type A sensitivity and a high-immunity build, it provides stable fault protection for EV chargers, pumps, small motors, and commercial appliances where B Curve devices may trip unnecessarily.
Installer Tip: Choose the 32A C Curve for heavier loads such as motors or EV chargers with high start-up currents. For general-purpose sockets or appliances, the 32A B Curve variant may be more appropriate.
Key Features
- 32A rated current – suited for heavier socket and appliance circuits
- C Curve tripping – handles higher inrush currents at start-up
- Type A sensitivity – detects AC + pulsating DC leakage
- High immunity design – reduces false trips from harmonics
- Compact 18mm width – space saving in tight boards
- Switched live & neutral – ensures full isolation under fault
- Bi-directional – suitable for PV and EV systems
Compare Mini RCBO Variants
| Model | Rated Current | Curve | Type | Width |
|---|---|---|---|---|
| WRB132B-030 | 32A | B Curve | Type A, High Immunity | 18mm |

What circuits suit the WRB132C-030?
It’s recommended for 32A circuits with higher inrush demand, such as motors, pumps, EV chargers, and commercial appliances.
What’s the difference between B and C Curve?
B Curve trips faster at lower fault currents, while C Curve tolerates higher inrush before tripping. Use the 32A B Curve for standard socket or appliance loads.
Is it compliant for renewable installs?
Yes – as a Type A device with high immunity, it’s suitable for EV and PV systems.
Does it fully isolate the circuit?
Yes – both live and neutral are switched, providing full disconnection under fault.
