RD3M, RD3P and RCQ020 residual current devices perform leakage current measurement through a frequency filtering that allows an increased immunity against high-frequency currents not hazardous to man that are typically generated by inverters and the main cause of unwanted tripping of. RD3M, RD3P and RCQ020 residual current devices perform leakage current measurement through a frequency filtering that allows an increased immunity against high-frequency currents not hazardous to man that are typically generated by inverters and the main cause of unwanted tripping of. ABB offers complete range of electronic residual current devices, in accordance the international Standard IEC6094 -2, Annex M. The perfect combination of RD3 and RCQ020 range with miniature circuit-breakers S200 family and Tmax moulded-case circuit- ensures residual current protection up to 12 0A. Residual current protection can detect and isolate the grounding (leakage) fault of low-voltage distribution networks in time, which is an essential technical measure to reduce electric shocks and fire accidents and improve power supply safety. The products and systems listed in this catalog are developed and manufactured using a certified quality management system in. The function of the Residual Current Protection Systems is to detect the leakage current caused by the insulation fault, to open the circuits they are connected to in case this leakage current exceeds the determined fault current value, and to remove the damage that may be caused by the leakage.
