Description

Broad range of monitoring relays to control voltage and current from Selec

The 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.



Order overview: Voltage monitoring relays

VPRA2MVPRA2M 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-2900VPR-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.


Order overview: Phase monitoring relays

MX-10 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.


Order overview: Current monitoring relays

900CPR1-1900CPR-1-1 current monitoring relay

Digital single phase AC current monitoring relay. Monitors over- and uncercurrent, up to 5A direct connection, over 5A connection with external current transformer.


900CPR3-1900CPR-3-1 current monitoring relay

Digital three phase AC current monitoring relay. Monitors over- uncercurrent and asymmetry, up to 5A direct connection, over 5A connection with external current transformers.
