Our Floor-Standing AC Power Distribution Boxes are engineered to serve as the primary power control hub for industrial plants, large commercial buildings, and utility infrastructures. Supporting a wide current range from 63A to 1600A, these modular cabinets provide the structural integrity and electrical safety required to manage high-current power distribution effectively.

Constructed from heavy-duty cold-rolled steel or galvanized plates, each cabinet is built to house high-amperage Air Circuit Breakers (ACB), Moulded Case Circuit Breakers (MCCB), and sophisticated monitoring equipment. The floor-standing design offers superior internal space for cable management, making it the ideal choice for facilities requiring a centralized, high-density power solution.

• Scalable Modular Design: The internal framework allows for flexible component layout, making it easy to upgrade or expand circuits as facility power demands grow.

• Heavy-Duty Structural Integrity: Features a reinforced steel frame (1.5mm–2.5mm thickness) capable of supporting heavy internal components like large busbars and 1600A breakers without warping.

• Tinned Copper Busbar System: High-conductivity T2 copper busbars are used to ensure minimal heat generation and maximum short-circuit withstand capacity (Icw).

• Advanced Thermal Ventilation: Equipped with natural ventilation louvers and optional smart-controlled cooling fans to ensure internal components operate within safe thermal limits.

• Environmental Protection: Rated at IP54/IP65, utilizing robotic foam-in-place gaskets to protect internal electronics from dust, moisture, and industrial pollutants.

1. Manufacturing Facilities: Main power feed for production lines, heavy motor control, and industrial HVAC systems.

2. Commercial Real Estate: Centralized distribution for shopping malls, hospitals, and high-rise office towers.

3. Data Centers: High-reliability power distribution for server racks and cooling infrastructure.

4. Renewable Energy: Main AC combiner station for large-scale solar farms or wind turbine power collection.

• Turnkey Customization: We build to your single-line diagram (SLD). Choose your preferred component brands (ABB, Schneider, Siemens, or CHINT) and cable entry orientation (Top or Bottom).

• Enhanced Safety Features: Includes internal arc-flash protection, physical partitioning between functional units, and lockable safety handles to prevent unauthorized entry.

• Easy Installation: The base channel design allows for quick anchoring to concrete floors, and the spacious interior ensures that terminating large-gauge feeder cables is fast and efficient.

• Pre-Shipment Testing: Every 1600A cabinet undergoes comprehensive insulation, grounding, and functional sequence testing in our factory to ensure "plug-and-play" reliability on-site.

Q: Can this cabinet handle dual power inputs (ATS)?

A: Yes. We can customize the cabinet to include an Automatic Transfer Switch (ATS) to manage power between a utility grid and a backup generator.

Q: What is the difference between a 630A and a 1600A model in terms of size?

A: While the modular height is often standard, the 1600A cabinet is typically deeper and wider to accommodate the larger Air Circuit Breakers (ACB) and the increased busbar cross-section required for high current.

Q: Do you offer the enclosure "Empty" for local panel builders?

A: Absolutely. We can provide high-quality standing enclosures with busbar supports and mounting plates for local assembly by system integrators.

Low voltage power distribution cabinet

XL-21 Low-voltage power distribution cabinet is suitable for power distribution of three-phase four-wire or three-phase five-wire system with AC voltage of 500 volts and below in power plants and industrial and mining enterprises. XL-21 low-voltage power distribution cabinet is installed against the wall of the indoor device, and inspected in front of the screen. The shell IS made of steel plate bending, and the knife switch handle is on the upper part of the right column in front of the box, which can be used for switching power supply. According to the needs of users, different types of circuit breakers with different current levels can be selected to meet the needs of different users.
