Power Distribution Panel (PDB)
POLARIS Power Distribution Panels (PDB) are designed to distribute electrical power from the main Power Control Centre (PCC) or transformer to sub-distribution boards, motor feeders, utility loads, and lighting circuits across industrial and commercial facilities. PDB Panels act as an intermediate distribution point, breaking down higher-capacity feeders into multiple controlled outgoing circuits. POLARIS PDB Panels are constructed with quality MCBs, MCCBs, and RCBOs depending on the load type, along with properly rated copper busbars, cable entry provisions, and metering where required. These panels are ideal for factories, warehouses, commercial buildings, and infrastructure where multiple load feeders need organised and protected distribution.
Key Features

Frequently Asked Questions
What is the difference between a PCC Panel and a PDB Panel?
A PCC (Power Control Centre) receives high-capacity incoming power from a transformer and distributes it to major feeders, while a PDB (Power Distribution Board) distributes that power further to individual sub-circuits, motor feeders, and utility loads. PDB Panels operate downstream of the PCC and handle lower current ratings.
What protection devices are used in POLARIS PDB Panels?
POLARIS PDB Panels use Miniature Circuit Breakers (MCBs), Moulded Case Circuit Breakers (MCCBs), and Residual Current Breaker with Overcurrent protection (RCBOs) depending on the connected load type, current rating, and safety requirements.
Can POLARIS design a PDB Panel based on my load schedule?
Yes. POLARIS custom-designs each PDB Panel based on your facility's load schedule, circuit ratings, feeder count, protection levels, and installation requirements. Submit your load details and our engineering team will prepare a detailed panel design.
Are POLARIS PDB Panels suitable for outdoor or semi-outdoor installation?
Yes. POLARIS offers PDB Panels with IP54 protection levels, weatherproof gaskets, and powder-coated enclosures for semi-outdoor or outdoor installation. For fully outdoor applications, feeder pillar panels with weatherproof construction are recommended.
What materials are used in the busbar of POLARIS PDB Panels?
POLARIS uses electrolytic-grade copper busbars with proper current density ratings to ensure low resistance, minimal heat generation, and high fault withstand capacity. Aluminium busbar options are also available based on project budget and load requirements.
