DC 6mA 4P Residual RCCB Circuit Breaker B Type For Wallbox Charger
Product Description:
Type B RCDs. Protection against shock and fire hazards during EV charging. Requires detection of AC and DC residual fault currents. This can be achieved by the use of dedicated RCDs, or by a combination of DC and/or AC residual current monitors with an A Type RCD or some other switching device.
