Block Diagram
Description
The KA2803B is designed for use in earth leakage circuit
interrupters, for stable operation of 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 that is
specified in KSC4613. The level comparator generates high
level when earth leakage current is greater than the fixed
level.
