Description
WCED WEV4100B-300 Bi-Directional B Type RCCB for Advanced Electrical Protection
The WCED WEV4100B-300 is a high-performance 4 Pole 100A B Type RCD 300mA designed for demanding commercial, industrial, EV and renewable energy installations. Engineered with advanced B Type sensing technology, this bi-directional RCCB detects AC, pulsating DC and smooth DC residual currents, making it suitable for modern electrical systems containing inverters, converters and electronic loads.
With a 300mA trip sensitivity, the WEV4100B-300 is intended primarily for fire protection and selective tripping applications rather than personal protection. Its bi-directional functionality makes it suitable for installations where power flow may occur in both directions, including solar PV and energy storage systems.
