Description

The Relion® RER620 is a compact and withdrawable recloser IED unit optimized for the protection, control and maintenance of overhead lines and cable feeders in industrial power systems with meshed or loop distribution networks as well as radial networks. It can be used to control both grounded and ungrounded distribution systems.

This model integrates three- and single-phase, multi-shot auto-reclose mechanisms to automatically restore the feeder in transmission lines that experience temporary failures. The unit implements IEC 61850 protocol for vertical and horizontal communication but is also compatible with other protocols such as DNP3.0, IEC 60870-5-101, IEC 60870-5-104 and Modbus®.
