A Sub Power Distribution Board (Sub PDB) is a secondary electrical distribution panel that receives power from a main Power Distribution Board (PDB) or Power Control Center (PCC) and distributes it to smaller circuits or localized loads within a facility. Sub PDBs are designed to provide efficient, safe, and organized power distribution for specific areas, floors, or equipment in industrial, commercial, and residential settings.
Sub PDBs are compact, modular, and engineered to handle lower current ratings compared to main PDBs, making them ideal for localized power management. They incorporate circuit protection devices to ensure safety, reliability, and compliance with electrical standards, while offering flexibility for customization to meet specific load requirements.
- Compact and Space-Saving Design : Optimized for localized power distribution, ideal for constrained spaces.
- High Safety Standards : Equipped with circuit breakers and residual current devices to prevent overloads, short circuits, and electrical hazards.
- Customizable Configurations : Available in single-phase or three-phase systems with multiple outgoing ways to suit specific needs.
- Robust Protection : Includes MCBs, RCBOs, and surge protectors to safeguard connected loads and ensure user safety.
- IP-Rated Enclosures : Offers IP54 (indoor) or IP65 (outdoor) protection against dust, moisture, and environmental factors.
- Ease of Installation : Designed with flexible cable entry points (top/bottom) and gland-type terminations for quick setup.
- High-Quality Construction : Built with 14/16 SWG CRCA sheets, powder-coated with a 7/9-tank process for corrosion resistance.
- Real-Time Monitoring (Optional): Digital meters for monitoring voltage, current, and power consumption.
Sub PDBs are equipped with essential components to ensure efficient power distribution and protection for localized loads. Key components include:
- Miniature Circuit Breakers (MCBs) : Protect individual circuits from overloads and short circuits.
- Residual Current Breakers with Overcurrent Protection (RCBOs) : Provide combined protection against earth faults and overloads for enhanced safety.
- Busbars : High-conductivity copper or aluminium busbars for efficient power distribution to outgoing circuits.
- Surge Protection Devices (SPDs) (Optional): Safeguard the system from voltage surges caused by lightning or grid fluctuations.
- Isolators/Switch Disconnectors : Allow safe disconnection of power for maintenance or emergencies.
- Metering Devices (Optional): Ammeters, voltmeters, or multifunction meters to monitor electrical parameters.
- Indicating Lamps and Control Switches : Provide visual feedback on circuit status and enable manual operation.
- Wiring and Terminals : FRLS/HR FR insulated wires and DIN-rail or stud-type terminals for secure and reliable connections.
- Enclosure : Durable, powder-coated CRCA steel or stainless steel enclosure for environmental protection.
