IL7101N TECHNICAL DATA IL7101N EARTH LEAKAGE CURRENT DETECTOR Description The IL7101N is designed for use in earth leakage circuit interrupters for operation directly oft the AC Line in breakers. It contains pre regulator, main regulator, after regulator, differential amplifier, level comparator, latch circuit. The input in the differential amplifier is connect to the secondary node of zero current transformer. The level comparator generates high level when earth leakage current is greater than some level.
