400100 Cable tray width

The 400100 cable tray has a width of 400 mm and a height (or depth) of 100 mm.

The 400100 cable tray, also referred to as SDH-400100 (KSS) or MT40010 (Schneider Electric), follows standard cable tray sizing conventions where the model number indicates its nominal width and height in millimeters . In this case, 400 mm is the inside usable width, and 100 mm is the side rail height or tray depth, which determines vertical stacking capacity and cable fill compliance .

Additional Specifications

• Length: Standard straight sections are typically 2–3 meters, but exact length depends on manufacturer and project requirements .
• Material Thickness: Varies by manufacturer; affects load capacity and allowable span .
• Tray Type: The 400100 is commonly a ladder or perforated tray, suitable for medium to heavy-duty cable runs, providing good ventilation and structural support .
• Cable Fill Considerations: NEC and IEC standards recommend a fill ratio of 40% for power cables and 50% for control cables, ensuring proper heat dissipation and future expansion .

Practical Notes

When selecting a 400100 cable tray, consider the number and type of cables, support spacing, and future expansion needs. The width of 400 mm allows for multiple large power or control cables, while the 100 mm depth provides adequate vertical clearance for proper cable management and airflow . This sizing ensures compliance with industry standards and facilitates safe, efficient installation in industrial, commercial, or data center environments.
