MPR500 is a motor protection relay that combines thermal overload, short circuit, undercurrent, unbalance, phase loss, phase sequence, lock/stall rotor and earth fault protections. MPR500 incorporates a 4-digit LED indicator which allows direct numerical readout of set values, actual measured value and system indication. MPR500 has 2 relay outputs (R1 and R2). R1 is On under normal operating condition to allow motor running, and off during tripping. R2 is programmable to give signal in various conditions. A programmable binary input is provided to perform various operations upon binary input triggering.
