Product description
Voltage monitoring relay Selec 900VPR-2-280/600V-CE-RoHS
The voltage monitoring relay 900VPR-2-280/600V-CE-RoHS from Selec for 3-phase systems monitors your system for under or overvoltage. The switching hysteresis and a possible time function can be easily set via the LCD display with backlight. For an alarm output, you have two NC or NO contacts available. The monitoring relay is simply mounted on 35 mm DIN-rail. The proven terminal connection of the 900VPR-2-280/600V-CE-RoHS voltage monitoring relay provides for easy wiring in your system.
