MCC motor control center/ PCC power control center

Motor Control Center (MCC)

The MCC is a low-voltage switchgear assembly designed for centralized control, protection, and monitoring of electric motors and other electrical loads. It ensures safe switching, overload and short-circuit protection, and integration with automation systems.

Key functions:

• Start/stop of electric motors (manual and automatic modes);
• Protection against overloads, short circuits, phase imbalances, and overheating; 
• Local and remote control; 
• Soft-start and speed regulation (using soft-starters or variable frequency drives);
• Visual/audible alarms for operational status;
• Fault condition indication; 
• Integration with SCADA systems.
• Hot-swappable modules (live replacement).

• AC power distribution circuits;
• Control circuits;
• Alarm and indication circuits;
• Measurement and monitoring circuits;
• Communication and integration circuits.

• Main incoming panel;
• Motor starter panel;
• Circuit breaker and automatic transfer switch (ATS) panel;
• Control and signaling panel;
• Cable entry panel;
• Communication panel.

Power Control Center (PCC)

The PCC is a low-voltage switchgear assembly designed for receiving, distributing, monitoring, and protecting electrical power in industrial, energy, and infrastructure facilities. It provides centralized power supply management for loads (including MCCs, distribution boards, and process systems) while ensuring line protection and integration with automation and metering systems.

Key functions:

• Power reception and distribution to outgoing lines;
• Protection of feeder lines against short circuits and overloads; 
• Busbar sectionalization (single or dual power supply); 
• Automatic transfer schemes (ATS);
• Energy metering;
• Status indication and alarms for lines and devices; 
• Built-in measurement and SCADA data transmission.

• Power circuits;
• Sectionalizing circuits;
• Measurement circuits; 
• Control circuits;
• Alarm circuits;
• Communication circuits.

• Sectionalizing panel;
• Distribution panel;
• Monitoring panel;
• Alarm and automation panel;
• Communication panel;
• Cable entry/exit panel.
