C Earth Leakage Detector COB (Ior-COB)

C earth leakage detector COB (Ior-COB) prevents an earth leakage breaking module from operating through the capacitive leakage current (Ioc).


Resistive leakage current [Ior] : Leakage current that flows because of an earth faultCapacitive leakage current [Ioc] : Leakage current that flows at all times through self-capacity without an earth faultCombined leakage current [Io] : Ior+ Ioc combined currentAs the existing earth leakage breaker is operated by the (Io) value of a composite leakage current, the breaker is often automatically cut off because of the Ioc that flows through the LED lamp, computer power, inverter, etc.There is no automatic trip in an C earth leakage detector COB (Ior-COB) as it has been designed to not operate in less than three times the Ioc current.Operating current of C earth leakage detector COB (Ior-COB) : Ior = 25mA / Ioc = 3 X Ior = 75mA
