Digital Motor Control and Energy Monitoring with MNS Switchgear

In the era of Industry 4.0, the demand for intelligent, connected, and energy-efficient power distribution is higher than ever. Traditional switchgear systems are no longer sufficient to meet the needs of modern manufacturing, smart infrastructure, or mission-critical facilities.

Enter the MNS Low Voltage Withdrawable Switchgear — a modular, intelligent platform that integrates digital motor control and energy monitoring to create a future-proof solution for both industrial and commercial applications.

This article explores how MNS digital motor control centers (MCCs) can transform your power infrastructure, reduce downtime, improve energy transparency, and support predictive maintenance.

What is a Digital Motor Control Center (MCC)?

A Motor Control Center (MCC) is a centralized system for controlling, protecting, and monitoring electric motors. Traditional MCCs rely on manual operation and relay-based logic. In contrast, digital MCCs use smart devices, communication networks, and real-time monitoring to automate control and diagnostics.

The MNS switchgear platform is ideal for building digital MCCs, thanks to its modular withdrawable design, high reliability, and compliance with IEC standards.

Integrated energy monitoring helps meet ISO 50001, LEED, and other sustainability standards.

Modular Withdrawable Units: Intelligent and Interchangeable

The withdrawable unit, or drawer, is the heart of the MNS system. Each unit can contain:

• Contactors

• Circuit breakers

• Overload relays

• Soft starters or VFDs

• Measurement modules

• Control logic

Intelligent Drawer Features:

• Pre-wired for plug-and-play installation

• Equipped with sensors and communication devices

• Hot-swappable design minimizes downtime

• Drawer status: connected / test / disconnected

Whether you're controlling fans, pumps, conveyors, or compressors, the MNS withdrawable circuit breaker system ensures modular, scalable, and safe control.

Use Case: MNS Digital MCC in a Shipyard

In shipyard manufacturing, hundreds of motors are used for:

• Hull welding automation
