The KA2803B 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 ZCT (Zero Current
Transformer). The amplified output of differential
amplifier is integrated at external capacitor to gain
adequate time delay specified in KSC4613. The level
comparator generates a high level when earth leakage
current is greater than the fixed level.
