Description
Broad range of monitoring relays to control voltage and current from SelecThe relays are monitoring the setpoint values and are signalising the over- or underexceedence of the preset values. Depending on the version the units have one or two changeover contacts.
The monitoring relays are mounted on a 35mm DIN rail.

VPRA2M One- or triphase voltage montioring relay
Analogue one- or triphase AC voltage monitor with neutral. Signalises overvoltage, undervoltage, phase loss, phase asymmetry and phase sequence.
900VPR-2 One- or triphase voltage montioring relay
Digital one- or triphase AC voltage monitor with or without neutral. Signalises overvoltage, undervoltage, overfrequency, underfrequency, phase loss, phase asymmetry and phase sequence.

600PSR Phase-monitoring relay from Selec
Monitors a 3-phase voltage without neutral. The device monitors the phase availability, correct phase sequence (U,V,W) and the phase voltage.
