Power Control Panel (PCC Panel)
POLARIS Power Control Panels (PCC) are high-capacity electrical distribution panels designed to receive incoming power from transformers or generators and distribute it safely to multiple outgoing feeders across industrial and commercial facilities. PCC Panels are the first major distribution point in an electrical system — making their design, protection, and build quality critical for the entire electrical infrastructure. POLARIS PCC Panels are built with Air Circuit Breakers (ACBs) or Moulded Case Circuit Breakers (MCCBs) for incoming protection, properly sized copper or aluminium busbars, outgoing feeder breakers, and protection relays for overcurrent and earth fault detection. Each panel includes energy metering, voltage and current indication, and optional PLC/SCADA connectivity. POLARIS ensures every PCC Panel is tested for dielectric strength, busbar temperature rise, and short-circuit withstand capacity before delivery.
Key Features

Frequently Asked Questions
What is a PCC Panel and what is its role in an industrial electrical system?
A Power Control Centre (PCC) Panel is the main electrical distribution panel that receives high-voltage power from a transformer or generator and distributes it to outgoing feeders for MCCs, sub-distribution boards, and other loads. It is the primary protection and control point for the entire facility's electrical system.
What type of circuit breakers are used in POLARIS PCC Panels?
POLARIS PCC Panels typically use Air Circuit Breakers (ACBs) for the incoming feeder and Moulded Case Circuit Breakers (MCCBs) for outgoing feeders. The selection depends on the panel current rating, fault level, and protection coordination requirements of the electrical system.
What protection features does a PCC Panel include?
PCC Panels from POLARIS include overcurrent and short-circuit protection, earth fault relays, under-voltage protection, and optional reverse power relays for DG-fed systems. These protections prevent equipment damage and ensure safe operation under fault conditions.
Can PCC Panels be used with both transformer and DG set power sources?
Yes. POLARIS PCC Panels can be configured for dual power source operation — receiving power from both a transformer (mains) and a diesel generator set. Auto changeover and bus coupler arrangements are designed into the panel as per project requirements.
What certifications and standards apply to POLARIS PCC Panels?
POLARIS PCC Panels are manufactured as per IS 8623 and IEC 61439-1/-2 standards. All panels undergo routine factory testing including dielectric tests, bus temperature rise verification, and protection relay setting checks before dispatch.
