Description
WCED 4 Pole 63A 30mA Type B RCD
The WCED WEV463B-030 is a high-performance WCED 4 Pole 63A 30mA Type B RCD designed for advanced electrical installations where both AC and DC residual current protection is required. Engineered for modern systems including EV charging, photovoltaic installations, UPS systems and frequency converters, this bi-directional RCCB provides enhanced protection against complex fault currents.
Unlike standard Type AC or Type A devices, the WEV463B-030 detects AC, pulsating DC and smooth DC residual currents including high-frequency leakage currents up to 1kHz. Its 30mA trip sensitivity provides personal protection and fault disconnection in demanding commercial and industrial applications.
