NHXS1B25
Wylex Single Pole + Switched Neutral Type A RCBO – 25A Protection with 30mA Earth Fault Detection
The Wylex Single Pole + Switched Neutral Type A RCBO offers comprehensive circuit protection by combining the overcurrent protection of an MCB with the earth fault detection of an RCD. With a 25A rating, 6kA breaking capacity, and 30mA sensitivity, this reduced-height RCBO is designed for use in domestic and similar installations. Fully compatible with Wylex NM Amendment 3 all-metal consumer units, ensuring compliance with 18th Edition wiring regulations.
- Type A RCBO Protection – Detects AC and pulsating DC residual currents for enhanced safety.
- Type B Tripping Curve – Trips between 3 to 5 times the full load current, ideal for residential circuits.
- 25A Rated Current – Suitable for protecting lighting and low-power electrical loads.
- 6kA Short-Circuit Capacity – Provides reliable fault protection in domestic installations.
- 30mA RCD Sensitivity – Rapidly detects and isolates earth faults to reduce the risk of electric shock.
- Single Pole + Switched Neutral Configuration – Disconnects both live and neutral for improved safety.
- Compact & Reduced-Height Design – Designed to fit Wylex NM Amendment 3 all-metal consumer units.
