Crouzet 84873222 3 Phase C-Lynx Voltage Monitoring Relay With 17.5mm SPDT Contacts, 3 x 208 - 480 V AC M3US, Under/Over H3US and M3US relays control, on 3-phase networks : Overvoltage between phases, Undervoltage between phases The H3USN relay controls, on 3-phase networks : Overvoltage between phases and neutral, Undervoltage between phases and neutral, Loss of neutral Multi-voltage Products Controls its own supply voltage True RMS measurement LED status indication 3-phase voltage controllers which monitor : Undervoltage, adjustable from -20 to -2 % of Un Overvoltage, adjustable from 2 to 20 % of Un Presence of the neutral (H3USN only) Measurements are taken between Phases for the H3US M3US and between Phases and Neutral for the H3USN Faults are signalled via LEDs, distinguishing the origin of the fault (one LED for the upper threshold, one LED for the lower threshold). Set the selector switch to the 3-phase network voltage Un. The position of this selector switch is only taken into account when the unit is powered up. If the switch position changes while the unit is operating, all the LEDs flash but the product continues to work normally with the voltage selected on energisation prior to the change of position. The LEDs return to their normal state if the switch is reset to its initial position defined before the last energisation.
