What is a Motor Control Center (MCC)? Structure and Applications
A Motor Control Center (MCC) is a control panel system in which numerous electric motors in a facility are powered, controlled, and protected from a single central point. It is indispensable, especially in industrial facilities with many motors.
MCC Structure
An MCC consists of modular withdrawable units or compartments, each controlling a motor. Each compartment typically contains the following components: motor protection switch, contactor, thermal relay or motor protection relay, and, if required, a soft starter or frequency inverter (VFD).
Fixed and Withdrawable Type MCC
- Fixed type: The sections are fixed to the panel; preferred in economical solutions.
- Withdrawable type: Motor sections can be inserted and withdrawn like a drawer; this allows other motors to continue operating while one motor is being serviced, thus shortening maintenance time.
Areas of Application
MCC panels are used in wastewater treatment plants, cement and mining plants, petrochemical, food, and automation-intensive production facilities. Devpan DevControl MCC panel solutions are designed for high operational continuity.
Frequently Asked Questions
What is the engine control center (MCC)?
MCC is a modular control panel system in which numerous motors in a facility are powered, controlled, and protected from a single central point.
What are the advantages of the withdrawable MCC model?
In withdrawable MCC motor housings, motor sections can be removed and reinserted, allowing other motors to continue operating while one is being serviced, thus shortening maintenance time.
Where is MCC used?
Wastewater treatment plants are used in multi-motor industrial facilities such as cement, mining, petrochemical, and food industries.
