Advanced microtech provides u-mpd, a microcomputer-based motor protection device. Salient features: separate indicator for fault annunciation single phase [in partial load as well], phase reversal, unbalance, overload and under load [dry run] protection: in-built auto sensing star delta timer [on motor current]: extra wide range [with single turn] to reduce inventory and maintenance - i -10 a, 7-20 a: and provides accurate overload protection by virtue of high release time accuracy. Other features: separate indicator for fault annunciation [spp. Ul. Ol, ub. Ph-r]; highly accurate tripping curve for full range of setting: in partial load for single phasing, accurate time for tripping action, that increases motor life; unbalance current protection [if the difference between any 2 phase > 40 percent ]; three cts for 3-phase measurement instead of two cts; extra wide range for set current [with single turn], i.E., [i to 10 a and 7 to 20 a] so. No inventory-, trip band is 1 percent and absolutely no nuisance tripping.
