The WCED WFR410B-030 is a 10A, B Curve, 4 Pole Type A RCBO designed to protect single- and three-phase circuits against overcurrent, earth leakage, and arc faults. With a switched neutral, it ensures full isolation of all conductors for safer testing, maintenance, and fault protection.
Rated at 10A, this RCBO is best suited for domestic and commercial lighting or small power circuits where fast disconnection is required. Its compact single-module design, bidirectional capability, and high immunity make it ideal for EV infrastructure, heat pumps, and solar PV installs.
Installer Tip: Use this B Curve 10A RCBO on lighting or small socket circuits where inrush current is minimal. For circuits with motors, inverters, or EV chargers, opt for the C Curve alternative to avoid nuisance tripping.
Key Features
- 10A, B Curve: Fast tripping for small resistive loads
- 4 Pole RCBO: Full isolation of live and neutral conductors
- Type A RCD: Detects AC and pulsating DC leakage
- Switched Neutral: Safer insulation resistance testing
- High Immunity: Stable with EV, solar, and inverter-driven loads
- Bidirectional: Safe for renewable energy systems
- Compact Design: Single DIN module (17.8mm)
- Compliance: BS EN 61009-1, BS 7671:2018 (18th Edition)

What’s the WFR410B-030 best for?
It’s ideal for 10A lighting or socket circuits where a fast trip characteristic is needed and full four-pole isolation is required.
What’s the difference between B and C Curve?
B Curve trips faster, ideal for lighting and resistive loads. C Curve tolerates higher inrush currents, making it better for motors, EV chargers, and renewable circuits.
Does this RCBO isolate neutral?
Yes – it features a switched neutral, ensuring complete disconnection and simpler testing.
Is it compliant with UK wiring regulations?
Yes – fully compliant with BS EN 61009-1 and the 18th Edition Wiring Regulations.
Can I use this in renewable/EV systems?
Yes – it’s bidirectional and high immunity, making it suitable for EV, solar, and heat pump circuits.
