Power Control Centre (PCC) panels are industrial-grade, metal-enclosed switchboards designed for 415V/690V 3-phase, 50Hz, 3/4 wire systems with current ratings up to 6300A. A PCC Panel (Power Control Center) is used for controlling and distributing electrical power in industrial and commercial systems.
It receives power from transformers or generators and distributes it to various loads.
PCC panels include components like circuit breakers, busbars, meters, and protection devices.
They provide protection against faults such as overloads and short circuits.
PCC panels ensure efficient, reliable, and centralized power management.
Standards: Conforms to IEC/IS standards (e.g., IS:4237, IS:2147, IS:3072).
Capacity & Rating: Up to 6300A current rating; 415/660 Volts operating voltage.
Construction: Air-insulated, floor-mounted, modular cubicle design using CRCA steel.
Busbar System: Electrolytic grade aluminum or copper, designed to meet fault levels of 50kA/65kA for 1 second.
Switchgear: Uses Air Circuit Breakers (ACBs) for incomers (often 4-pole EDO type) and Moulded Case Circuit Breakers (MCCBs) for outgoing feeders.
Protection: IP42 (standard indoor) up to IP65 (outdoor) protection against dust and water.
Protection Features: Microprocessor-based, offering overload, short-circuit, and earth fault protection.
