XL Non-standard Distribution Box Dimensions

XL non-standard distribution boxes, such as XL3-N and Eaton XBoard series, offer flexible dimensions tailored to specific installation needs, with metal enclosures, reversible doors, and customizable internal layouts.

XL3-N Series (250–630 A)

The XL3-N distribution boxes are designed for professional electrical installations and comply with IEC 61439-2 standards. Key dimensional and structural features include:

• Material & Finish: Metal construction, grey RAL 7035, smooth corners for easier handling .
• Enclosure Options: Supplied with surface mounting box, door with handle, and faceplate. Doors are reversible for flexible installation .
• Internal Layout: Fully isolated tin-plated copper busbars, insulated earth, and neutral terminal blocks with holes equal to the number of outgoing circuits .
• Rated Specifications: Maximum voltage 415 V±, rated peak current up to 110 kA, ambient temperature 50°C continuous .
• Customization: Knockouts for cable glands, optional IP41 kit for additional protection, and compatibility with MCBs up to 63 A . Exact length, width, and height for non-standard XL3-N boxes are typically customized per project requirements, but standard XL3-N enclosures range in modular widths to accommodate 1–36 ways, with mounting depth and height adjustable via internal mounting plates .

Eaton XBoard Series

The Eaton XBoard (XDB) series provides a modular approach for low-voltage power distribution:

• Construction: Robust 2 mm sheet steel, fully shrouded 250 A main isolator with safety interlock .
• Rated Current & Breaking Capacity: Rated current up to 630 A, rated breaking capacity 20 kA .
• Design Flexibility: Available as assembled or unassembled boards, allowing field customization. Internal layouts can be adapted for specific applications, including sub-distribution or motor control .
• Dimensions: While exact non-standard dimensions are project-specific, the XBoard series supports compact and energy-efficient designs with flexible mounting and internal spacing for circuit breakers and terminal blocks .

Summary

XL non-standard distribution boxes are highly customizable in terms of dimensions, internal layout, and mounting options. For precise measurements, it is recommended to consult the manufacturer's technical datasheets or configurator tools to select the appropriate enclosure size, number of ways, and internal components for your specific installation . These boxes are ideal for industrial and commercial applications requiring robust, flexible, and standard-compliant electrical distribution solutions.
