MDmax ST Intelligent Digital Power Distribution System

MDmax ST High-Safety Low-Voltage Switchgear

MDmax ST is an ABB MDmax ST TTA Low-Voltage Switchgear, a fully type-tested (TTA) modular low-voltage switchgear system developed by ABB. It complies with IEC 61439-2 and GB/T 7251.2 standards.

Built on a 25 mm standardized modular G-profile aluminum-zinc coated steel frame, the system integrates four core advantages: enhanced safety protection, digital intelligent power distribution, high-density modular design, and long-term durability.

The product covers a current range from 400A to 6300A, and supports flexible configurations including incoming feeders, outgoing feeders, reactive power compensation, and motor control integration. It is widely applied in industrial manufacturing, renewable energy, municipal infrastructure, data centers, and commercial buildings, making it a mainstream solution for mid-to-high-end low-voltage power distribution systems.

Advantages and Features

• Full-Parameter Real-Time Monitoring: Equipped with multifunction meters, wireless temperature sensors, and arc flash detectors, the system captures 200+ electrical parameters and contact temperatures at millisecond intervals, providing complete, no-blind-spot visualization of equipment status.

• AI Predictive Alerts: Using operational data modeling, the system can predict overheating, loose connections, and aging 7–30 days in advance with an accuracy exceeding 95%, significantly reducing unplanned downtime.

• Circuit-Level Energy Management: Supports precise metering, harmonic analysis, and power factor optimization, unlocking 12–18% energy savings potential and supporting carbon neutrality initiatives.

• Seamless Multi-Protocol Integration: Compatible with Modbus, Profinet, MQTT, and can be integrated with DCS, EMS, and BMS platforms, enabling remote monitoring and mobile app-based operation & maintenance.
