DESCRIPTION

The GL7101 is designed for use in earth leakage circuit interrupters for operation directly off the AC line in breakers. It contains pre-regulator, main regulator, after regulator, differential amplifier, level comparator, and latch circuit. The input in the differential amplifier is connected to the secondary node of zero current transformer.

The level comparator generates high level when earth leakage current is greater than some level.
