Description
The WRN32C-030 is a 32A Type A RCBO with a C-curve tripping characteristic, supplied in a single-module, 2-pole format. Combining residual current (RCD) and overcurrent (MCB) protection, it safeguards circuits against AC and pulsating DC leakage. The built-in switched neutral ensures both live and neutral are disconnected on fault, keeping installs compliant with BS 7671 (18th Edition) while improving site safety.
Installer Tip: A 32A C-curve RCBO is often specified for higher load appliance circuits, small submains, or equipment with high inrush currents, where a B-curve model could nuisance trip.
- 32A C-Curve RCBO: Suited to circuits with higher starting currents
- Type A protection: Trips on AC and pulsating DC residual currents
- Compact design: Single 18mm module width
- 2-pole switched neutral: Full isolation of live and neutral
- Minimises disruption: Only faulty circuits are disconnected
- BS 7671 compliant: Meets 18th Edition Amendment 2

FAQs
When should I use a 32A C-curve RCBO?
It’s suited to higher load appliance circuits, small submains, or equipment with higher inrush currents, such as pumps and compressors.
What’s the benefit of C-curve over B-curve?
C-curve devices handle higher inrush currents without nuisance tripping, whereas B-curve is used for standard domestic loads like sockets and lighting.
Does this device isolate neutral as well as live?
Yes — the switched neutral disconnects both conductors during a fault, improving site safety and compliance.
Will this fit into a standard consumer unit?
Yes. At only 18mm wide, it’s compatible with most UK DIN rail consumer units and distribution boards.
Is this fully compliant with UK regulations?
Yes. The WRN32C-030 is certified to BS EN 61009-1 and meets the 18th Edition Amendment 2 requirements.
When should I choose a B-curve instead of this C-curve?
If the circuit is a general domestic load with low inrush, such as lighting or sockets, the WRN32B-030 B Curve RCBO may be a better fit.
