Overview
The PR260 motor protection controller adopts a modular design with a small footprint, allowing for a spliced combination of functional modules and offering a flexible structure, suitable for standard rail installation with an external high current transformer and adaptable to various applications. It consists of the following components:
Main control module (mandatory): This is the core component responsible for overall control and protection.
Measurement module (mandatory): This module measures key parameters such as current, voltage, and power. It also includes connecting cables for integration with the motor. With the built-in residual current transformer in the measurement module, the PR260 electric motor protective relay can be easily installed without additional wiring.
Switching module (optional): This switching module provides additional switching capabilities for specific applications.
Display module (optional): This display module (HMI) utilizes a dot matrix LCD and highlighted indicator lights to clearly show operating status and data. offers a visual interface for monitoring the motor’s status and parameters. With the connecting cables, it can easily connect to the main control module.
Feature of PR260 Motor Protection Relay
Our economical & reliable Multifunction motor protection relay has up to 21 motor protection functions, including current imbalance, over current, under current, current leakage, overcurrent stall, Phase unbalance, Reverse Phase, phase failure, ground fault, short circuit, overload, under load, start overtime, jam in starting, under power, external failure, over temperature, over-voltage, under voltage, abnormal frequency, abnormal power factor, restart, tE protection, overflow failure, Lock or Stall, etc. Moreover, Moreover, each motor protection function is capable of realizing shutdown, alarm, or tripping.
The PR260 electric motor protection relay offers high-accuracy metering and monitoring for power (active power, reactive power, apparent power), voltage (phase voltage, sequence voltage, line voltage, etc), current (over current, under current, phase current, sequence current, lock current, ground current), Earth Fault, frequency, energy, and Power Factor, etc. The relay for motors stores the latest 100 event records for measuring data.
The PR260 electric motor protection relay offers various communication options like Two Wire RS485, Profibus, and Ethernet ports. Thus, it supports a wide range of industry-standard protocols, including Modbus RTU, Modbus TCP, IEC61850, Profibus, and EtherNet/IP. In summary, equipped with communication modular and I/O modular, PR260 is a versatile motor protection relay that offers robust networking capabilities, supports multiple protocols, and can be easily integrated into various industrial automation systems.
From an industry view, the PR260 motor protection controller is a pre-configured solution for industrial and utility applications such as water management & sewage, material handling, oil &gas, mining, automotive, telecom, machinery, other industrial automation sites, etc.In terms of specific applications, it is mainly used for low voltage three-phase electric asynchronous (induction), synchronous motors, IEC or NEMA class motors, and AC Motors. The motor is usually used in motor-independent control boxes or MCC (motor control center) control cabinets, Fans, Pumps (water pumps, well recovery pumps), compressors, cranes, air conditioners, and refrigerators so all these applications need to protect motors from failure. PR260 can be your advanced automation motor protection and control solution.
