Motor Control Centre (MCC)

---

An MCC is a physical assembly of combination starters, which are enclosures that house motor-starting equipment, circuit protection devices, and power disconnecting devices. It allows for centralized control and monitoring of multiple motors from a single location1.

Key Features:

Modularity: MCCs are modular, allowing for easy expansion and customization.

Motor Starters: Includes various types of motor starters such as Direct On Line (DOL), Star Delta, Soft Starters, and Variable Frequency Drives (VFDs).

Circuit Protection: Equipped with circuit breakers, fuses, and overload relays to protect motors from electrical faults.

Control Components: Features control components like push buttons, indicator lights, and programmable logic controllers (PLCs).

Safety: Includes safety interlocks and arc barriers to protect operators and equipment.

Applications:

MCCs are commonly used in:

Industrial Facilities: To control and protect motors used in manufacturing processes.

Commercial Buildings: For managing motors in HVAC systems, elevators, and other building services.

Power Plants: To control motors used in power generation and distribution.
