Crouzet 84873024, 3 Phase Voltage Monitoring Relay With 17.5mm SPDT Contacts, 3 x 208 - 480 V AC MWA, Sequence, Failure, Imbalance (asymmetry), Under/Over

Overvoltage between phases,
Undervoltage between phases

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
Asymmetry, adjustable from 5 to 15% of Selected 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.

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.
