AC Voltage Protection Relays

AC voltage relays, UVR, OVR, CVR, PFR series - click to enlargeA range of DIN rail or surface mountable relays for the voltage monitoring and protection of AC mains or generator systems.

Variants are available for protection against over and/or under voltage, for either single phase, 3 phase and neutral, or 3 phase no neutral systems.

Each unit features a front facia "trip volts" adjuster to set the relay de-energisation point. UVR, OVR and CVR models also have "differential volts" setting for control of the relay energisation voltage.

Features:

  • Under and/or over AC voltage protection
  • Single phase & neutral, 3 phase & neutral, 3 phase no neutral options
  • Front facia "trip volts" adjuster sets relay de-energisation
  • Front facia "diff volts" adjuster sets relay re-energisation (except PFR)
  • DPDT relay outputs, rated 5 Amp @ 240 VAC
  • LED indication of relay state
  • DIN rail/surface mout case, screw terminals
