Description
WCED 4 Pole 100A B Type RCD 300mA Trip
WCED WEV4100B-300 4 Pole 100A B Type RCD
The WCED WEV4100B-300 is a heavy-duty 4-pole, 100A B Type RCD with a 300mA trip sensitivity. Unlike 30mA devices used for personal protection, this unit is designed for fire protection and advanced system safety, detecting AC, pulsating DC, and smooth DC currents.
Engineered for demanding installations, it carries a 6kA short-circuit rating, IP20 ingress protection, and BS EN 61008-1 compliance. The 300mA rating makes it suitable for distribution systems, EV, and renewable installations where discrimination and fire prevention are critical.
