Earth Leakage Detector

KA2803

Description

The KA2803 is designed for use in earth leakage circuit interrupters,

for operation directly off the AC line in breakers. The input of the

differential amplifier is connected to the secondary coil of Zero

Current Transformer (ZCT). The amplified output of differential

amplifier is integrated at external capacitor to gain adequate time

delay. The level comparator generates a high level when earth leakage

current is greater than the fixed level.
