PSR-A-3

Suitable for three phase unbalance / three motor control. It has Input voltage, output voltage, phase reversal, neutral break, motor lock, auto function failure protection & also has six input i.e. low cut and high cut control for each of three motor. Correction is done on both phase – phase & phaseneutral voltage. The input & output trip contact can be configurable as per MCCB with shunt trip & contactor on site.
