ABB Relion REC615

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

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.

Modular and flexible

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.
