| Voltage monitoring relay VPRA2M | ||
Description
Analogue voltage monitoring relay form selec. Controls one or three pase voltage with neutral. Monitors overvoltage, undervoltage, phase asymmetry, phase failure and phase sequence.Easy setting with three front knobs with sealable cover. Slim space saving design, only 35mm wide. 35mm DIN Rail mount.
Settings The following three sealable front knobs are used for the VPRA2M settings:
OV: Trip setting overvoltage 105 to 125%
UV: Trip setting undervoltage 95 to 55%
T: Trip Time Settings for undervoltage, overvoltage and phase loss 0 to 15s
