3 Phase Voltage Protection Relay Over-Voltage Failure SPDT Three 220V 380V 480V 127-254V AC EKR8 (3 Phase 4 Wire,7110 (AC220-480V))

relayRelayVoltage protection relay uses a high-speed and lowpower processor as its core. When the power supply line has over-voltage under-voltage or phase failure phase reverse the relay will cut off the circuit quickly and safely to avoid accidents caused by abnormal voltage being sent to the terminal appliance. When the voltage returns to the normal value the relay will turn on the circuit automatically to ensure the normal operation of the terminal electrical appliances under unattended conditions1. Cut off the line when Over & Under Voltage occurs and automatically reset and connect the line after returning to normal without manual operation2 When the line appears transient or transient Over Under Voltage the protector does not malfunctionEKR870103Phase 3Wire 0 knob SPDT Voltage Range: 380V ACEKR8-7110:3Phase 3Wire 1 knob SPDT Voltage Range: 220V 230V 240V 380V 400V 415V 440V 460V 480V ACEKR8-7310:3Phase 3Wire 3 knob SPDT Voltage Range: 220V AC / 380V ACEKR8-741N:3Phase 4Wire 4 knob SPDT Voltage Range: 127V 132V 138V 220V 230V 240V 254V ACHOW TO CHOOSE THE MODELProduct CodeOver VoltageUnder VoltageDelay TimePhase SequencePhase Failure701015%15%3s/ YES7110/ / 3s/ YES73100%~20%0%~20%0.1s~10sYESYES741N0%~20%0%~20%3sYESYES
