How LS Electric EMPR Is Revolutionizing Motor Protection

LS Electric EMPR: The Next Generation of Motor Protection Relays


LS Electric is committed to advancing the field of motor protection and supporting the Industrial Internet of Things (IIoT). As part of this commitment, the company is continually developing new products and features that support IoT connectivity and enable businesses to optimize their operations.




As a digital motor protection relay with MCU, EMPR is highly reliable by implementation of real-time data processing and high precision and also can secure motor safely with various functions such as phase loss, phase reverse, unbalanced, stall, lock, ground fault, short circuit protection depending on the model . EMPR has compact and simple appearance so it can be combined with the magnetic contactor. Various installation methods and separation of terminal block make easy design and manufacturing feature for MCC(Motor Control Center)





Gone are the days of relying on simple overcurrent relays or fuses to protect motors. With LS Electric EMPR Beyond Motor Protection...the new EMPR IMP series support MODBUS RS-485 communications or 4~20mA analogue output and are the most economic and reliable solution


In addition, LS Electric EMPR can be easily integrated into existing automation systems, making it a cost-effective solution for businesses seeking to upgrade their motor protection capabilities. Its flexible configuration options, including adjustable trip settings and communications protocols, make it suitable for a wide range of applications and industries.

The EMPR IMP series are optimal solutions for protecting and monitoring motors in complex industrial fields and provide high safety and productivity.

● Where monitoring panel for the MCC is required

● Where reliability and stable protection are needed







LS Electric EMPR is an electronic motor protection relay that is widely used in various applications to protect electric motors from damage due to overloads, phase failures, and other electrical faults. This advanced relay not only provides reliable protection for motors, but it also supports IoT (Internet of Things) connectivity, making it a valuable tool for industries seeking to optimize their operations and reduce downtime. Applications such as :


● Semiconductor, chemical, automobile, textile and pharmaceutical plants

● Oil, gas, railway, water supply/drainage, and buildings

● Steel, cement, paper and ship building




The LS Electric EMPR is designed to protect motors from a range of electrical faults, including overloads, phase imbalances, and phase losses. This is achieved through advanced algorithms that monitor the motor's performance in real-time and trigger an alarm or trip the motor if any fault is detected. This prevents damage to the motor, reducing maintenance costs and downtime.



The LS Electric EMPR also supports IoT connectivity, enabling it to be integrated into the Industrial Internet of Things (IIoT). This means that it can be remotely monitored and controlled, providing real-time data on motor performance, energy consumption, and fault diagnostics. This data can be used to optimize motor performance, reduce energy consumption, and predict maintenance needs, further reducing downtime and increasing productivity.






In conclusion, LS Electric EMPR is an advanced electronic motor protection relay that provides reliable protection for electric motors while also supporting IoT connectivity. Its real-time monitoring and diagnostics capabilities make it a valuable tool for industries seeking to optimize their operations and reduce downtime. With its wide range of applications and advanced features, LS Electric EMPR is an essential component of any modern industrial facility.
