Phase monitor 320-460V, 1 NO - Phase monitoring relay 185...460V CMPVE1SVR550870R9400 – ABB – 1SVR550870R9400 – 4013614348105: Phase monitor 320-460V, 1S CMPVE1SVR550870R9400 Design of the electrical connection screw connection, rated control supply voltage Us at AC 50 Hz 185... 460V, rated control supply voltage Us at AC 60 Hz 185... 460V, type of voltage for actuation AC, phase failure detection function, undervoltage detection function, overvoltage detection function , voltage measuring range 185... 460V, min. adjustable response delay time 0.5s, max. permissible response delay time 0.5s, min. adjustable off-delay time 0.5s, max. permissible off-delay time 0.5s, number of contacts as NC contacts 0, number of contacts as NO contact 1, number of contacts as changeover contact 0, width 22.5mm, height 78mm, depth 78.5mm, the relay monitors networks for overvoltage and undervoltage and phase failure. If all phases are present (the neutral conductor) and the correct voltage is present, the output relay picks up after the switch-on delay ts has expired. If the voltage to be monitored exceeds or falls below the fixed threshold value or if a phase failure occurs, the output relay drops out after the tripping delay has elapsed. If the voltage returns to the tolerance window, the output relay will automatically pick up after ts has elapsed. The yellow LED lights up when the output relay is activated
