Motor protection and control REM615 ANSI

Reliability, security, and dependability with Relion®

The REM615 ANSI is a dedicated motor relay perfectly aligned for the protection, control, measurement and supervision of asynchronous motors in generation plants and manufacturing and process industries.

REM615 is a member of ABB's Relion product family and a part of its 615 protection and control product series. The 615 series relaysare characterized by their compactness and withdrawable design. Engineered from the ground up, the 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability between substation automation devices.
