ABB REM610 Motor Protection Relay

Overview

The ABB REM610 motor protection relay is designed to protect, measure, and supervise medium to large asynchronous low-voltage (LV) motors and small to medium-sized high-voltage (HV) motors. Part of the Relion® 610 product family, it provides robust protection for motors in manufacturing and process industries. The relay supports various communication protocols and is well-suited for both new installations and retrofits.
