The WCED WFR432C-030 is a 32A, C Curve, 4 Pole Type A RCBO that provides combined overcurrent protection and earth leakage protection in one compact device. Featuring a switched neutral, it guarantees complete isolation of all conductors, meeting BS 7671 (18th Edition) compliance requirements.
With its C Curve tripping profile, this RCBO is optimised for high inrush circuits such as EV chargers, motors, HVAC equipment, solar inverters, and commercial lighting banks. Built with bidirectional, high immunity electronics, it ensures reliable operation in demanding residential, commercial, and renewable energy installations.
Installer Tip: Choose the 32A C Curve for circuits with heavy inrush currents. For resistive or lightly inductive loads, consider the 32A B Curve version for faster disconnection.
Key Features
- 32A, C Curve: Handles high inrush loads
- 4 Pole Isolation: Disconnects all live conductors plus neutral
- Type A RCD: Detects AC and pulsating DC leakage
- Switched Neutral: Safer insulation resistance testing
- High Immunity: Reduces nuisance tripping under electronic loads
- Bidirectional: EV & renewable-ready
- Compact: Single-module DIN rail mount (17.8mm)
- Compliance: BS EN 61009-1, 18th Edition Wiring Regulations

What’s the WFR432C-030 best for?
It’s best suited for 32A circuits with high inrush demand such as motors, HVAC systems, EV chargers, and solar inverters.
What’s the difference between B and C Curve?
B Curve trips faster on resistive loads like sockets and lighting, while C Curve tolerates higher inrush before tripping, making it ideal for motors and renewable setups.
Does this RCBO fully isolate?
Yes – it disconnects all live conductors plus neutral via the switched neutral design.
Is it EV and renewable ready?
Yes – it’s bidirectional and high immunity, making it suitable for EV chargers, solar PV, and inverter-based systems.
Is it compliant with UK standards?
Yes – tested to BS EN 61009-1 and compliant with the 18th Edition Wiring Regulations.
