HJ-PDB Series Floor-Standing Power Board
Up to 800A / Floor-Standing / Secondary Distribution
The HJ-PDB Series Floor-Standing Power Board is a highly reliable, compact, and cost-effective secondary distribution solution. Engineered for robust performance in industrial and commercial environments, it provides safe and efficient power routing, motor control, and lighting distribution for loads up to 800A, ensuring smooth operation at the facility floor level.
Ideal for Floor-Level Power Distribution:
- ✓ Manufacturing Workshops & Assembly Lines
- ✓ Commercial Buildings & High-Rise Facilities
- ✓ Water Treatment & Pumping Stations
- ✓ Mining, Metallurgy & Light Industrial Plants
1. Robust Floor-Standing Architecture
Built to withstand demanding industrial environments. The enclosure is constructed from high-strength folded steel profiles (C-profile or 8MF), providing exceptional structural rigidity. Its fully enclosed design effectively shields internal components from dust, debris, and accidental contact.
2. Flexible Component Integration
Tailor your power board to exact load requirements. The HJ-PDB effortlessly accommodates a wide range of switching and protection devices, including Molded Case Circuit Breakers (MCCBs), Miniature Circuit Breakers (MCBs), contactors, thermal relays, and fuses. It supports optional earth-leakage (residual current) protection modules for enhanced safety.
3. Safe Front-Access Operation
Designed for user-friendly maintenance. The switchgear features a clean, intuitive front-panel layout with clear voltage/current indicating meters, signal lights, and control switches. All routine operations, inspections, and maintenance can be performed safely from the front of the board.
4. High Cost-Efficiency for Secondary Grids
The HJ-PDB is optimized to deliver maximum value for secondary power distribution. By utilizing a simplified fixed-mounted structure without complex withdrawable mechanisms, it significantly reduces your initial capital expenditure (CAPEX) while delivering decades of reliable, maintenance-free service.
Global Factory Acceptance & Turnkey Support
Every HJ-PDB unit undergoes comprehensive routine testing, including insulation resistance and functional sequence validation, before dispatch. We deliver the panels as CBU (Completely Built Units), fully wired and ready for immediate floor mounting and cable termination at your project site.
