PR 260 Motor Protection Relay

PR 260 Motor Protection Relay

PR 260 Motor Protection Relay is a modular design motor management device, that accommodates more I/O modules. This digital motor protection relay is a flexible arrangement of motor control modes and state sensing. As for monitors voltage, current, and temperature, this intelligent motor protection relay provides a comprehensive package of 22 protective functions. It is with integrated protection, motor control, metering, and data-logging functions.

This electronic motor protection relay is typically used to provide protection for three-phase low- and medium-voltage, medium to high-horsepower induction motors.
