PR 260 Motor Protection Controller Motor Protection Relay

PR 260 Motor Protection Controller

The modular PR 260 Motor Protection Controller is a motor management device that can hold numerous I/O modules. The product’s status detection and motor control modes are arranged flexibly. Furthermore, PR260 keeps an eye on temperature, voltage, and current in addition to offering a full range of 22 protection features. Integrated protection, motor control, metering, and data logging are just a few of its features.

Usually, three-phase induction motors with medium to high horsepower and low to medium voltage are protected by this Motor Protection Controller.
