Wall Mounted Stainless Steel Electrical Junction Boxes 100A~630A Distribution Box

The XL-21 (Low-Voltage Power Cabinet) and JXF (Wall-Mounted Junction Box) series represent the industry standard for reliable power distribution in commercial and industrial settings. Built from premium-grade stainless steel, these enclosures are engineered to protect critical electrical components—such as breakers, meters, and contactors—from harsh environmental factors.

Whether you are managing a factory floor, a commercial basement, or a high-rise residential project, our XL-21 and JXF series provide a flexible, modular, and high-strength solution for power loads ranging from 100A to 630A.

• High-Grade Stainless Steel Construction: Available in SS304 or SS316L, providing maximum resistance to corrosion, rust, and chemical exposure. Ideal for coastal areas, food processing plants, and high-humidity environments.

• Superior Sealing & Protection: Featuring a precision laser-welded body and a high-resilience polyurethane sealing strip. The JXF series achieves up to IP65/IP66 protection, while the XL-21 floor-standing units offer IP40/IP54 for heavy-duty indoor power management.

• Flexible Internal Mounting: Equipped with a removable, galvanized mounting plate (orange or white) and adjustable DIN rails, allowing for the rapid installation of MCCBs, MCBs, and terminal blocks.

• Advanced Safety Design: Includes dedicated copper grounding studs (Earth points) on both the door and the body, ensuring electrical continuity and operator safety.

• Professional Ventilation: For high-current 630A applications, the XL-21 units can be configured with louvered vents and integrated cooling fans to prevent heat buildup and extend component lifespan.

1. Industrial Manufacturing: Acting as the main power feed for production lines and heavy machinery.

2. Commercial Real Estate: Serving as meter junction boxes and floor distribution boards in office towers and shopping malls.

3. Water Treatment & Infrastructure: Protecting pump controllers and monitoring equipment in damp environments.

4. Food & Beverage Industry: Providing hygienic, easy-to-clean electrical cabinets that withstand frequent washdowns.

• Turnkey Customization: We provide "empty enclosures" or fully wired "complete sets" based on your specific Single Line Diagram (SLD).

• Precision CNC Fabrication: Our automated production line ensures that every door hinge, lock, and gland plate fits perfectly, eliminating the need for on-site adjustments.

• Heavy-Duty Hardware: We use industrial-grade concealed hinges (130-degree opening) and high-quality zinc-alloy locks to ensure the cabinet remains secure and functional for decades.

• Expert Packaging: All units are shipped in reinforced plywood crates or heavy-duty cartons with edge protection to ensure they arrive at your project site in pristine condition.

Q: What is the difference between XL-21 and JXF?

A: XL-21 is typically a larger, floor-standing power cabinet used for main distribution (up to 630A). JXF is a more compact, wall-mounted box used for sub-distribution, junctions, or local control (up to 250A).

Q: Can these boxes be used outdoors?

A: Yes. When ordered in Stainless Steel 304/316 with an IP65 rating, the JXF series is fully capable of withstanding direct rain and UV exposure.

Q: Do you offer custom sizes?

A: Absolutely. While we have standard dimensions (e.g., 600x800x200mm), we can manufacture custom heights, widths, and depths to fit your specific space constraints.

    JXF series distribution box is suited for operating in the circuit of AC 50Hz, rated operating voltage 500V and below, in some special cases, the protection grade can reach up to IP55, the top and bottom of the panel will provide knockout holes, if multiple pipes are used for incoming lines, opening plate can be prepared, maxi rated current up to 400A, especially suitable for usage in metering and control box of mining field, hotel, living buildings and etc. Comply with GB7251.12-2013 Low voltage switchgear and controlgear, IEC60439-2:2011 Low voltage switchgear and controlgear standard.
