BE1-27, BE1-59, BE1-27/59, Voltage Relay

These relays provide a reliable response to protect power system equipment from adverse voltage conditions.


  • Immediate protection response to extreme voltage conditions with instantaneous functions.
  • Timings can be tailored to the application with individually adjustable definite, short inverse, medium inverse, or long inverse timing for each time-delayed under/overvoltage function.
  • Flexible pickup is continually adjustable over a wide range.
  • Minimized PT costs as a result of low sensing burden.
  • Reduced battery load with low burden power supply.
  • Accurate, repeatable, and reliable operation.
  • Simple HMI provides clear and intuitive settings for easy configuration.
  • LED targets provide clear annunciation of status.
  • Easily perform in-case system and device tests using test paddles.
