Motor Protection Devices

Advanced Microtech offers Motor Protection Devices, m-MPD-TUA. It is of microcomputer based provided with a separate indicator for fault annunciation. It has highly accurate tripping curve for full range of setting. It contains partial load for single phasing, accurate time for tripping action, which increases motor life. It offers unbalance current protection (if the difference between any 2 phase > 40%), three CTs for 3-phase measurement instead of two CTs, extra wide range for set current (with single turn). Trip band is 1% and absolutely no nuisance tripping. Less inventory, flexibility to user by having wide range, isolated from power connection, so no burning, environmental temperature does not affect on tripping curve it is very accurate, over and under load protection, setting by potentiometer; in-built auto scanning Star Delta timer (on motor current), in case any fault occurs (SPP, Ub, OL, UL, Ph-r) and power fails fault condition store in memory, after power restore motor does not restart; and repairable.
