PR 260 electronic motor protection relay 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, provides a comprehensive package of 22 protective functions. The over-current relay has some functions, including integrated protection, motor control, metering, and data logging.
This electronic overload relay is typically used to protect three-phase low-and medium voltage, medium to high-horsepower induction motors.
