SR489-P5-HI-A20-E | GE Multilin Generator Management Relay

Description

Technical Specifications

The 489-P5-HI-A20-E is a generator management relay that is manufactured by GE Multilin as part of the 489 Generator Management Series.   This relay has 5A phase CT secondaries and a HI control power of 90-300 VDC and 70265 VAC at 48-62 Hz.  The analog outputs on this relay are 4 to 20 mA.  This 489-P5-HI-A20-E relay has an enhanced display with a larger LCD than the basic display generally serves as an upgrade from the 489-P5-HI-A20 basic display version. The 489-P5-HI-A20-E is the most installed relay in the 489 Generator Protection Series and as a result is a high demand relay.  The 489-P5-HI-A20-E has the following features built-in to the relay. Trip and Alarm Protection Metering Breaker Failure Flash Memory Trip Coil Supervision VT Fuse Failure Simulation The 489 Enervista 489PC Software is utilized along with the 489-P5-HI-A20-E to allow the user to interact and program the relay from a PC.  This Software is included in New Factory Package versions of the 489-P5-HI-A20-E.  Additionally, a SR489-CASE draw-out case is included with new 489-P5-HI-A20-E and can be included with refurbished relays upon request.  Manuals and other manufacturer documentation on the 489-P5-HI-A20-E is available from GE Power Management and GE Multilin.

The Multilin™ 489 Generator Protection System, a member of the SR family of relays, provides protection,control and advanced communications in a cost effective industry leading draw-out construction.Designed for small and medium sized generators, the 489 delivers advanced protection includinggenerator stator differential protection. The 489 also includes detailed diagnostic information allowingfor reduced troubleshooting time.
