ABB Relion REC615

Comprehensive protection and control relay for recloser applications in overhead line networks, Modular and flexible

ABB Relion REC615

ABB Relion REC615 is a freely configurable all-in-one protection and control relay for recloser applications in overhead line networks. The ABB Relion REC615 is a grid automation relay for protection and control, monitoring, fault indication, automation, and power quality analysis in medium-voltage secondary distribution systems, including networks with distributed power generation, with secondary equipment such as medium-voltage disconnectors, switches, ring main units and reclosers.  

The design of the ABB Relion REC615 relay has been guided by the IEC 61850 and ANSI standards for communication and interoperability of substation automation devices. 

ABB’s protection and control 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 repair, retrofit and upgrade projects. 

 

The ABB Relion REC615 relays feature a draw-out-type design with a variety of mounting methods, compact size and ease of use.  REC615 offers two different relay size variants, standard and wide. Relay size variant and module content can be selected according to application needs. Relay application functionality can be selected independently from the selected hardware content according to the protection application needs. ABB Relion REC615 leverages the same configuration software as all ABB Relion protection and control products.  

Cybersecure and digital-ready, ABB Relion REC615 supports various communication protocols for high-speed protection, fault isolation and restoration and optimal cyber security to promote secure connectivity and safeguard today’s network.

Frequently Asked Questions

That is correct. There will be no new releases of RER615 and RER620. REC615 represents the next step, including also recloser control applications.

Yes. The standard‑size Relion REC615 has identical mechanical dimensions to REC615 and RER615 relays, while the wide‑size Relion REC615 has identical dimensions to RER620. Hardware dimensions and mounting kits are the same.

Yes. REC615 standard offers the same analog and binary channels as REC/RER615, and REC615 wide offers the same channel capabilities as RER620. No wiring adapters are required.

REC615 supports protection and control applications, including recloser control. It can be used with ABB reclosers such as OVR‑15, OVR‑27, OVR‑38 and GridShield.

Yes. REC615 supports multiple SCADA communication protocols, including IEC 61850, IEC 101/104, DNP3 and Modbus. An external radio or modem may be required depending on the communication method.

Yes. REC615 is engineered using ABB’s PCM600, providing a familiar engineering environment and consistent lifecycle management for Relion relay users.

REC615 offers seven application packages, and any combination of packages can be freely selected regardless of the relay hardware. This allows flexible adaptation to different needs and requirements.

Yes. REC615 is designed for flexibility and long‑term use. Application packages, logic, and hardware modules can be added or modified throughout the relay’s entire life cycle using ABB’s PCM600.

Yes. REC615 has been developed in compliance with IEC 62443‑4‑1 and is designed and tested according to IEC 62351 and IEC 62443‑4‑2. It also undergoes dedicated vulnerability testing by ABB’s Device Security Assurance Center (DSAC).

Yes. Both hardware and software are fully modular. Additional application packages and hardware modules can be added or changed throughout the relay’s entire life cycle using PCM600.
