PCC Panel (Power Control Center)
The heart of main power distribution in any plant or facility.
Function: Receives incoming main supply directly from the transformer or DG set and distributes high power through feeders to various sub-panels (including MCCs).
Key Components: Main Air Circuit Breakers (ACB), Busbar systems, Protection Relays, and Energy Meters.
Core Role: Power Distribution & Feeder Management.
MCC Panel (Motor Control Center)
The nerve center for industrial motor operation.
Function: Receives power from the PCC panel to control, run, and protect industrial electric motors.
Key Components: Contactors, Overload Relays, Motor Protection Circuit Breakers (MPCB), and Variable Frequency Drives (VFD).
Core Role: Motor Control (Start, Stop, Speed Regulation & Protection).
- PCC = Distributes Power
- MCC = Operates Motors
Seperate panels ensure higher reliability, safe fault isolation, easier maintenance, and better plant safety.
