Can I select a trefoil cleat from cable cross-section alone?
No. Provide the complete cable outside diameter in mm, the trefoil drawing and the required cleat assembly. Equal conductor sizes can have different cable diameters.
Trefoil Cable Cleat
Trefoil cable cleat for three single-core cables arranged in a triangle. Match cable outside diameter, mounting details and the required restraint evidence to the selected model.

Trefoil cable cleat model selection
A trefoil cleat holds three cables in the triangular arrangement defined by the installation drawing. This entry uses SKU SW-0647 and lists a diameter-range reference of Φ40–150mm. Treat that as a catalog selection range: confirm the individual model size and clamping range for the actual cable diameter.
| Input | Required check |
|---|---|
| Cable formation | Three single-core cables in the approved trefoil layout; send a section drawing. |
| Cable diameter | Outside diameter of each cable in mm, including the outer sheath. |
| Cleat assembly | Selected model, material, liners, closure parts and included fasteners. |
| Mounting | Support dimensions, hole positions, fasteners and horizontal or vertical orientation. |
| Restraint duty | Peak current, RMS current, duration, cleat spacing and applicable test configuration. |
Diameter fit and short-circuit performance
Conductor cross-section does not establish cable outside diameter. Read the cable datasheet or measure the complete cable at the installation location, then compare it with the selected cleat range and liner arrangement.
IEC 61914 covers cable cleat requirements and tests, including electromechanical restraint where declared. Request documentation for the proposed model and configuration. A broad catalog range or standard reference does not establish one short-circuit rating for all sizes.
Younxin’s available cleat documentation includes short-circuit reports for YY-T2405 and YY-Q3340. These reports apply to the tested models and configurations; confirm whether the proposed assembly is covered. Review single, trefoil and quad cleat selection and use the IEC 61914 procurement checklist to prepare the data.
Specify the complete cable restraint order
For distributors, list each model and size separately, including liners, fasteners, package quantities and labels. For a project, provide the cable schedule, route layout, support details and required documents. Keep intermediate restraints and mounting hardware as separate BOM lines where specified.
Compare other cable cleats and clamps by formation and dimensions. Confirm any substitution against the approved installation and documentation.
