M3PRC/S-4W [HV]
- Under and Over voltage monitoring (Window)
- Suited to High Voltage supplies – 575V or 600V
- Detects incorrect phase sequence, phase and neutral loss
- Adjustable Trip levels and Time delay
- SPDT Relay output
- 35mm wide, DIN Rail mount
The product monitors it’s own three-phase supply and for the output relay to energise, all phases (and neutral) must be present, the phase sequence correct and the phase to neutral voltages within the set Under/Over trip levels. If any of these conditions are not met, the relay will de-energise.
