Product description

The SR489-P5-HI-A20 is a generator management relay manufactured by GE Multilin and is part of the 489 generator management family. The relay has 5A phase CT secondary and HI control power of 90-300 VDC and 70265 VAC (48-62 Hz). The analog output on this relay is 4 to 20 mA. This 489-P5-HI-A20-E relay features an enhanced display with a larger LCD than the base display and is often used as an upgrade to the 489-P5-HI-A20 base display version.

The SR489-P5-HI-A20 is the most installed relay in the 489 generator protection series and is therefore a highly demanding relay. The relay has the following functions built into the 489-P5-HI-A20-E.
