... V R ©2002 Fairchild Semiconductor Corporation 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 trip time of breaker is decided by the capacitor C This capacitor should be selected under 1 F for the required the trip time. The full wave bridge supplies power to the KA2803B during both the positive and negative half cycles of the line voltage. This allows the hot and neutral lines to be interchanged. ...
