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.
