PR260 Earth Leakage Relay Electronic Motor Protection Relay Overload leakage current relay

Description

PR 260 is a motor management device of modular design, accommodating many I/O modules. The product can flexibly arrange motor control modes and state sensing. In addition, PR260 monitors voltage, current, and temperature, provide a comprehensive package of 22 protective functions. It has some functions, including integrated protection, motor control, metering, and data-logging.

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