Description
WCED WEV263B-030 Bi-Directional B Type RCCB for EV & Advanced Electrical Systems
The WCED WEV263B-030 is a high-performance 2 Pole 63A 30mA Type B RCD designed for advanced electrical installations requiring protection against AC and DC residual fault currents. Engineered for modern applications including EV charging, photovoltaic systems, UPS equipment and inverter-driven loads, this bi-directional RCCB delivers reliable fault protection in demanding environments.
Unlike standard Type AC or Type A devices, the WEV263B-030 detects AC, pulsating DC and smooth DC residual currents, including high-frequency leakage currents up to 1kHz. Its 30mA trip sensitivity provides additional protection against electric shock and automatic disconnection under fault conditions.
