HYCA type AC DC leakage current sensor

HEYI Electrical company ASCT brand new product HYCA type AC DC leakage current sensor is a Leakage Protection Residual Current sensor specifically developedfor EV-charging providing all-current sensitivity. Charging of electric vehicles ata standard wall socket or a wall box requires protection devices against DC faultcurrents to avoid electric shock. Installed type A residual current circuit-breakers(RCCBs) are unable to identify and deactivate DC fault currents.
