Residual current circuit breakers EFI are used for protection against indirect touching of parts under voltage, for prevention of lasting voltage on earthed parts which should appear because of a defect in the electrical installation and for protection against direct contacts of parts under voltage in case of I∆n≤30mA. Residual current circuit breakers can be used in TN-S, TN-C, TT and IT network systems or with other words in all systems where neutral and protective conductor are separated (VDE 0100 Part 410).
