The GE 489-P5-HI-A20-E is a generator management relay, manufactured by GE Multilin for the 489 series. The relay has a 5 A phase CT secondary coil. The high control power supply is 90-300 volts DC and 70265 volts AC at 48-62 Hz. The relay has an analogue output of 4 to 20 mA.The relay has an enhanced display with a larger LCD than the basic display. It is the customer's responsibility to ensure proper insulation levels if low voltage applications require output relay contacts.
