Our 3-Phase Low Voltage Power Distribution Cabinet is a versatile, high-protection solution designed for centralized power management in both indoor and demanding outdoor environments. Engineered to handle currents from 32A up to 300A, this metal steel box serves as the primary or secondary distribution hub for industrial machinery, construction sites, and commercial infrastructure.

The standout feature of this series is its IP55-rated construction, which ensures the internal components—such as MCBs, MCCBs, and RCBOs—are shielded from dust ingress and low-pressure water jets. Whether you require a standard configuration or a fully customized internal layout, our steel cabinets provide the structural integrity and electrical safety required for modern power grids.

• IP55 Weatherproof Integrity: Features a high-quality, continuous polyurethane foam-in-place (FIP) gasket on the door and a specialized rain-hood design, making it suitable for damp or dusty industrial settings.

• Rugged Steel Construction: Fabricated from 1.5mm to 2.0mm thick cold-rolled steel or galvanized steel. The CNC-folded seams and fully welded body provide superior mechanical strength (IK10 impact rating).

• Flexible Amperage Support: The internal busbar and component mounting system are designed to accommodate various load profiles, including 32A, 63A, 100A, and 300A configurations.

• Superior Corrosion Resistance: Treated with a multi-stage chemical pickling process followed by a high-durability electrostatic epoxy powder coating (Standard RAL 7035), ensuring the cabinet remains rust-free for years.

• Enhanced Safety Grounding: Equipped with dedicated copper earth studs on the body, door, and mounting plate to ensure total electrical continuity and operator protection.

1. Industrial Workshops: Providing localized 3-phase power for CNC machines, welding stations, and heavy-duty compressors.

2. Commercial Buildings: Main or sub-distribution for lighting, HVAC, and elevator circuits in malls and office towers.

3. Construction & Temporary Power: Rugged, weatherproof hub for power distribution on job sites where dust and debris are prevalent.

4. Renewable Energy Projects: AC combiner boxes or distribution points for commercial solar PV installations and battery storage systems.

• Bespoke Internal Layouts: We provide custom-drilled mounting plates and DIN rail arrangements based on your specific Single Line Diagram (SLD).

• Component Versatility: We can populate the cabinet with high-quality switchgear from global brands like Schneider, ABB, and Chint, or deliver empty enclosures for your own assembly.

• Thermal Management: For higher-current 300A models, we offer optional side ventilation louvers and internal heat shields to ensure components remain within safe operating temperatures.

• Secure Locking Mechanism: Features a high-strength chrome-plated swing handle with a 3-point locking system to prevent unauthorized tampering.

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.
