GE MULTILIN 489 - 489-P1-HI-A20-E Generator management relay
The GE Multilin 489-P1-HI-A20-E is a microprocessor-based relay designed for the protection and management of synchronous and asynchronous generators. It is suitable for primary or backup protection of small and medium-sized generators and can be used in cogeneration applications. Model number 489-P1-HI-A20-E, it operates with 1A phase CT secondaries and has a control power of 90-300V DC or 70-265V AC (48-62 Hz). It has 4-20 mA analog outputs and an extended LCD display. It has advanced protection functions such as stator differential protection, loss of excitation, reverse power protection, over-excitation, breaker failure protection and thermal monitoring. It provides safe and efficient operation of generator systems by measuring current, voltage, power, energy, frequency and power factor. EnerVista 489 Setup software provides easy configuration and monitoring.
