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.

Undervoltage threshold delay
The relay monitors its own supply voltage. It controls :
Undervoltage, adjustable from - 2 to - 20 % of Un (-2 to -12 % over the 3 x 220 V ∿ range due to the minimum voltage 194 V ∿)
Overvoltage, adjustable from + 2 to +20 % (+2 to +10 % over the 3 x 480 V ∿ range due to the maximum voltage 528 V ∿). Each threshold has its own time delay with independent setting between 0.3 and 30 s. In the event of a voltage fault, the corresponding relay (one undervoltage output/one overvoltage output) opens at the end of the time delay set by the user. In the event of phase failure, both relays open instantaneously, without waiting for the end of the time delay. The two relay LEDs go out. The relay monitors its own supply voltage. It controls :
Presence of the neutral, - Undervoltage, adjustable from -2 to -20 % of Un, - Overvoltage, adjustable from +2 to +20 %. Each threshold has its own time delay with independent setting between 0.3 and 30 s. In the event of a voltage fault, the corresponding relay (one undervoltage output/one overvoltage output) opens at the end of the time delay set by the user. If neutral is lost, both relays open instantaneously and the corresponding LED is extinguished, without waiting for the end of the time delay. The two relay LEDs are extinguished.

Application Notes
Relay in 3-phase main monitors size of phase voltage. It is possible to set two independent voltage levels and thus it is possible to set two independent voltage levels and monitor e.g. undervoltage and overvoltage independently. In normal state when voltage is within set levels, output relay is closed and red LED shines.
In case voltage exceeds or falls below the set levels, output relay opens and red LED shines ( LED indicates faulty state – flashes when timing). In case supply voltage falls below 60 % Un (UOFF lower level)relay immediately opens without delay and faulty state is indicated by red LED.In case timing is in progress and faulty state is indicated, timing is immediately stopped.
