Power Monitoring Relays
Three phase monitoring relays
Eight models available with different combinations of detection and protection functions as per the following table of model type versus function.
Photograph shows a Multi-Voltage unit for detection of Faulty Phase Sequence/ Total Loss of Phase(s)
Detection of wrong phase sequence
Detection of total absence of one, two or threee phases
Detection of more than 20% voltage drop of the nominal voltage in one phase.
Detection of more than 40% voltage drop of the total nominal voltage.
Dection of loss of neutral or ground
Detection of loss of asymmetry (rate adj. 5-20%)
Thermistor Motor Protection
Protection against high voltage impulses
Multi Voltage (3 x 200VAC nom. to 3 x 500VAC nom.)
