The WCED WFR416C-030 is a 16A, C Curve, 4 Pole Type A RCBO that integrates MCB protection and RCD protection in a single device. With a switched neutral, it guarantees full isolation of all conductors during faults or testing, meeting BS 7671 (18th Edition) standards.
The C Curve tripping profile makes this RCBO suitable for circuits with moderate to high inrush currents, including motors, pumps, EV chargers, solar inverters, and HVAC systems. Its bidirectional, high immunity design ensures stable performance in both residential and commercial installations where reliability is critical.
Installer Tip: Choose the 16A C Curve when circuits are expected to experience inrush currents. For resistive or low-inrush applications, opt for the 16A B Curve version.
Key Features
- 16A, C Curve: Handles moderate/high inrush loads
- 4 Pole Isolation: Disconnects live and neutral conductors
- Type A RCD: Detects AC and pulsating DC leakage
- Switched Neutral: Ensures safe testing and fault isolation
- High Immunity: Minimises nuisance tripping under electronic loads
- Bidirectional: Suitable for EV, solar, and inverter systems
- Compact: Single-module DIN rail fit (17.8mm)
- Compliance: BS EN 61009-1, 18th Edition Wiring Regulations

When should I use the WFR416C-030?
It’s best suited for 16A circuits with moderate to high inrush, such as motors, HVAC, or solar inverter systems.
How does the C Curve differ from B Curve?
C Curve tolerates higher inrush currents before tripping, while B Curve responds faster on resistive loads.
Does this RCBO fully isolate the circuit?
Yes – it disconnects all live conductors and the neutral via its switched neutral design.
Is this device EV/renewable ready?
Yes – its bidirectional, high-immunity design is compatible with EV chargers, solar, and inverter systems.
Is it compliant with UK regs?
Yes – it’s tested to BS EN 61009-1 and fully compliant with the 18th Edition Wiring Regulations.
