M54128FP - EARTH LEAKAGE CURRENT DETECTOR

General Description

The M54128 is a semiconductor integrated circuit designed for high-speed type earth leakage breakers.

This lC includes leakage and abnormal voltage detecting functions.

Key Features

  • q lmprovement of ability against unwanted tripping due to Iightning -surge.
  • Adopt the two times counting system.
  • lmprovement of ability against needless action due to lightningimpulse. q lt is a possible that cope with lEC owing to mode change.
  • Adopt the 1.5 times counting system. q High input impedance :.
  • Filter circuit can be formed with externally attached C/R.
  • lmprovement of ability against needless action due to high frequency and high harmon.
