VOLTAGE SENSING RELAY (UVR) 3 Phase 300-003-ST

Voltage Sensing Relay UVR 300-003-ST. Voltage sensing relay as used in our UVR controlled ATS panels 3 phase voltage monitoring relay for phase failure detection. This relay provides both under and over voltage protection as well as phase sequence of the supply being monitored. The relay has an adjustable nominal input voltage level range from 208, 220, 380, 400, 415, 440 to 480 (phase to phase)   making it suitable for use in many worldwide countries with different supply voltages to the UK. Under voltage adjustment -5% to -25% of nominal Overvoltage adjustment 5% to 25% of nominal SPCO output relay 5A @ 250V Din rail mounting, 17.5mm wide
