KA2803BDTF - Brand New Fairchild Semiconductor Power Management Specialized - PMIC
-
Description
The KA2803B is an electronic component model designed for use in earth leakage circuit interrupters. It ensures stable operation of the AC line in breakers by connecting the input of the differential amplifier to the secondary coil of ZCT (Zero Current Transformer). The amplified output of the differential amplifier is integrated with an external capacitor to provide an adequate time delay, as specified in KSC4613. The level comparator generates a high level signal when the earth leakage current exceeds the fixed level.
