£37.19
The WCED WFR4 Series is a 4 Pole Type A RCBO range covering 6A to 40A ratings, with both B and C curve options. These devices combine residual current protection and overcurrent protection in one unit, providing full disconnection of live and neutral conductors for...
4 Pole B-Type RCDs
£158.30
The WCED 4 Pole Type B RCD is designed to provide advanced protection for circuits where smooth DC and high-frequency fault currents are present. Fully compliant with IEC/EN 62423, it safeguards against both AC and DC residual currents up to 1000 Hz, making it suitable...
2 Pole A-Type 100mA Time Delay RCD
£25.35
The WARTD Series A-Type 100mA Time Delay RCD is designed for upstream fault protection in dual-RCD or discrimination setups. Often referred to as an S-Type RCD, its built-in delay ensures downstream devices trip first, preventing unnecessary loss of power across unaffected circuits. Suitable for both...
4 Pole A-Type 100mA Time Delay RCD
£30.25
The WCED 4 Pole A-Type 100mA Time Delay RCD is designed for installations requiring selectivity between upstream and downstream RCDs - commonly referred to as RCD discrimination. With 100mA sensitivity and a built-in time delay, these devices help ensure only the correct device trips in...
