Low Voltage Power Distribution Box 3 Phase AC380V Main Switch Distribution Box

The XL-21 Series Power Distribution Cabinet is a versatile, closed-type indoor distribution solution engineered for AC 50/60Hz systems with rated voltages up to 415V. Renowned for its structural rigidity and simple layout, the XL-21 serves as a primary power receiver and feeder for industrial plants, mining operations, and commercial workshops.

This cabinet is designed to provide comprehensive protection against overloads, short circuits, and leakage. Its spacious internal design makes it the industry standard for housing Moulded Case Circuit Breakers (MCCB), contactors for motor control, and metering equipment. Whether used for light-load power distribution or as a centralized motor control center, the XL-21 provides a secure, IP-rated environment for your critical electrical infrastructure.

• High-Strength Structural Steel: Fabricated from cold-rolled steel plates with a thickness of 1.5mm to 2.0mm, ensuring the cabinet remains undeformed under the mechanical stress of heavy cabling.

• Flexible Component Integration: The internal mounting rails are adjustable, allowing for the seamless installation of international brands like Schneider, ABB, and Siemens or cost-effective domestic alternatives.

• Superior Safety Interlocking: Features a robust door-handle linkage system that ensures the cabinet remains securely locked during operation, preventing unauthorized access to live busbars.

• Efficient Heat Dissipation: Designed with natural ventilation slots on the side or door, optimized to maintain stable internal temperatures even when fully loaded.

• Ease of Installation: Equipped with bottom or top cable entry plates and a dedicated earthing busbar (PE), simplifying on-site wiring and ensuring consistent grounding.

1. Industrial Workshops: Centralized distribution for production machinery and industrial lighting circuits.

2. Motor Control Centers: Housing DOL (Direct-On-Line) starters and Star-Delta configurations for pumps and fans.

3. Commercial Infrastructure: Reliable power hubs for shopping malls, hospitals, and high-rise basement substations.

4. Mining & Heavy Industry: Rugged protection for power systems in dusty or high-vibration environments.

• Anti-Corrosion Finish: Every cabinet undergoes a multi-stage pickling and phosphating process followed by a high-durability epoxy powder coating (Standard RAL 7035), resisting rust and scratches for over 20 years.

• Smart Metering Options: We can pre-configure the front panel with digital multi-function meters for real-time monitoring of current, voltage, and power factor.

• Custom Wiring Service: We offer fully wired "Turnkey" panels, pre-tested in our facility for insulation resistance and functional continuity, allowing for "Plug-and-Play" site installation.

• Compact Footprint: The XL-21 is designed to offer maximum circuit density while maintaining a slim profile, making it ideal for cramped electrical rooms.

Q: Is the XL-21 suitable for outdoor installation?

A: The standard XL-21 is designed for indoor use (IP40). However, we can provide a modified version with a rain hood, outdoor-grade seals, and an IP54/IP55 rating for sheltered outdoor environments.

Q: What is the maximum breaker size I can fit in this cabinet?

A: The XL-21 typically accommodates main breakers up to 630A. For requirements exceeding 800A, we recommend our GGD or GCS series switchgear.

Q: Can I request a specific RAL color for my project?

A: Yes. While light gray (RAL 7035) is our standard, we can provide any RAL color to match your facility's existing electrical equipment.
