The MH OUV 400 is an over and under- voltage relay for industrial and commercial application. It is used in a wide variety of voltage sensitive equipment such as 3-phase AC motor, pump and ventilation fan require a balanced supply voltage to operate efficiently.

FEATURES:

  • Over voltage limit protection
  • Under voltage limit protection
  • Microprocessor controlled DTL operation
  • Backlit high contrast LCD display
  • Wide operating range AUX voltage
  • 4 Trip event records
  • Sealable tamper proof front cover
