Entry-level feeder protection and control relay

ABB Relion REF601 is an entry-level feeder protection and control relay for secondary distribution. ABB Relion REF601 protection and control relay offers main protection for overhead lines and cable feeders in solidly earthed, resistance-earthed or isolated networks.  ABB Relion REF601 also offers serial communication (Modbus RTU and IEC-103) for easy connection. It is compliant with IEC/ ANSI/CN and CEI standards.

ABB’s protection relays are available for original equipment manufacturers (OEM), panel builders and Engineering, Procurement and Construction (EPCs) partners to incorporate in their own installations or for use in new, retrofit or upgrade projects. 

 

 

Basic protection

It provides an optimized composition of protection, monitoring and control functionality in one unit, including pre-configured functionality for easy and fast commissioning of medium voltage switchgear.  To emphasize the simplicity of relay’s usage, only application specific parameters need to be set within the relay’s intended area of application.  

 ABB Relion REF601 leverages the same configuration software as all ABB Relion protection and control products.
