REF610C55LCNR Feeder Protection Relay

The feeder protection relay REF610 is a versatile multifunction protection relay
mainly designed to protect incoming and outgoing feeders in a wide range of feeder
applications.
The relay is based on a microprocessor environment. A self-supervision system continuously monitors the operation of the relay.
The HMI includes a liquid crystal display (LCD) which makes the local use of the relay safe and easy.
Local control of the relay via serial communication can be carried out with a computer connected to the front communication port. Remote control can be carried
out via the rear connector connected to the control and monitoring system through the serial communication bus.
