The WRN16C-030 is a 16A Type A RCBO with a C-curve tripping characteristic, supplied in a compact single-module, 2-pole design. It combines residual current (RCD) and overcurrent (MCB) protection in one device, detecting AC and pulsating DC leakage currents. With a switched neutral included, it ensures complete disconnection of live and neutral conductors during a fault, helping installers meet BS 7671 (18th Edition) compliance.
Installer Tip: Choose a C-curve RCBO when circuits have higher inrush currents — for example, small motors, pumps, or refrigeration equipment. A B-curve device may nuisance trip under these conditions.
- 16A C-Curve RCBO: Designed for circuits with higher inrush loads
- Type A protection: Detects AC and pulsating DC leakage currents
- Space-saving single-module width: 18mm design
- 2-pole with switched neutral: Fully isolates live and neutral
- Minimises disruption: Only the faulty circuit disconnects
- 18th Edition compliant: Meets BS 7671 Amendment 2 standards
When should I use a C-curve RCBO instead of a B-curve?
Use a C-curve RCBO on circuits with higher inrush currents, such as small motors, pumps, compressors, and refrigeration equipment. B-curve models are suited to lower inrush circuits like sockets and lighting.
What does the switched neutral provide?
It ensures both live and neutral conductors are disconnected on fault, improving safety and compliance during maintenance and testing.
Is this device suitable for consumer units?
Yes - the single 18mm module width fits standard UK DIN rail consumer units and distribution boards.
Does it comply with UK wiring standards?
Yes. The WRN16C-030 complies with BS EN 61009-1 and is fully suitable for installs under the 18th Edition Amendment 2 regulations.
When should I choose a B-curve instead of this C-curve?
If the circuit is a standard domestic load with low inrush, such as sockets or lighting, the WRN16B-030 B Curve RCBO may be the better fit.
