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 harmonics. q High input sensitivity : VT = 6. 5mVrms q Abnormal voltage detecting (neutral conductor open-phase protection) function : • Neutral conductor open-phase protection at single-phase threewire system • ln case of no use...
