Core Product Features
Integrated design: Integrates motor protection, measurement and control, communication, and logic control into a single module, significantly simplifies secondary wiring of low-voltage cabinets, and reduces construction and failure probabilities.
Distributed intelligent operation and maintenance: Each motor is independently locally protected, and the bus network is centralized for networking, enabling intelligent management, energy consumption statistics, and predictive maintenance of low-voltage motor equipment throughout the plant.
Drawer-type plug-and-play: No need to reconfigure parameters when replacing the drawer, and modules support local parameter storage, resulting in high operational efficiency.
Compatible with ABB System 800xA DCS platform, widely compatible with power plants, chemical plants, and metallurgical MNS low-voltage complete switch cabinets.
Rich fault alarms: Local LED fault indicator + remote background event upload, enabling rapid identification of the cause of motor tripping.
