GKR-02 Voltage Monitoring Device Relay Phase Failure and Phase-Sequence Protection for Motor Din Rail

relayCircuit BreakersGKR-02 Voltage Monitoring Device Relay GKR-02 Phase Failure And Phase-sequence Protection Relay For Motor ProtectionGeneral GKR ve DGR series "over and under voltage" moitoring devices are adjustable "delay OFF"protection devices. they are mainly used for protection for 3-phase and single-phase systems-such as electronic command and control systems capacitors fo power compensation switch-boards air-condition systems motors etc.Utilization and Operation PrinciplesFor all relays"on" is the supply led"out" is normal led"U>"is over voltage error led<;;"is under voltage errror led1-When the device is energized for the first time."On" led is ON and if the monitored voltageare within the adjusted range "Out" led is ON and output relay switches ON.<;;" error led turns ON after 0.1-10sec output relay switched OFF and "OUT" led turns OF.3-When any of the phase/phases exceed(s) the adjusted interval "U>" error led turns ON after0.1-10 sec output relay switches OFF and "Out"led turns OFF.look at table 1*For under voltage monitoring device switched OFF its output relay instantaneously when the measured voltage(s) fall(s) below 50% of its nominal value.For over voltage monitoring device switches OFF its output relay immediately when the measured voltage(s) exceeds 50% fo its nominal value.GKR-02F /GKRC-02F/ GKRC-02FA /GKR-03F/GKRC-03F/ switches off output relay instantaneously in case of incorrect phase sequence then all leds turn off except "ON" led.Technical Data:Rated voltage(Un) Look it the label of the device Rated frquuency 50/60Hz Operating range (0.9-1.1)×Un Voltage adjustment Max: (1 05-1 03) ×Un Min: (0 70-0 95) ×Un Delay time 0.1-10sn.min.(adjustible) Output contact 1C/O 8A 2000VA Set point hysteresi
