KK54123

GROUND FAULT INTERRUPTER EARTH

LEAKAGE CURRENT DETECTOR

Description

The

KK54123N/D

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, latch circuit. The input in the differential amp

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.
