Motor Protector

The motor protection device is developed by our company through years of production technology research on similar foreign products and comprehensive integration of domestic MCC electrical systems, designed with high-performance digital microprocessor technology for motor protection and control. It features internationally advanced motor protection functions, supports professional motor control methods, and provides precise monitoring capabilities, enabling various controls, operational monitoring, protection, interlocking, measurement, remote communication, telemetry, remote control, and fault information management for motors.

 The motor protection device is protected by intellectual property and software copyrights, significantly improving design and production efficiency while greatly reducing on-site debugging and equipment maintenance costs for users. It is a multifunctional product for motor protection, providing scientifically effective on-site protection and measurement and control units for production processes.

The motor protection device adopts a modular design structure, with a compact size and structure, suitable for rail or bolt installation, and can be directly installed in various fixed cabinets and drawers. It provides protection and control for three-phase asynchronous motors and increased safety motors, making it an ideal product for three-phase motor protection in industries such as chemical, petroleum, power, mining, coal, metallurgy, municipal, papermaking, nuclear industry, and many others.
