Panduit CCALTR3438-X Aluminum Trefoil Cable Cleat
The Panduit CCALTR3438-X delivers IEC 61914:2015-certified short circuit protection for trefoil-configured power cables in industrial, utility, and datacenter installations. Engineered for aluminum cable armor in medium to high fault current environments, this cleat retains cables through fault events up to 114kA peak—preventing catastrophic cable whip and system damage during three-phase short circuits. The trefoil design supports bundled cable diameters from 34–38mm (1.34–1.5"), with direct cable-tray rung mounting via M8 bolts. Ships in 10-packs for full-run installations.
Key Features
- IEC 61914:2015 certified and tested to 114kA peak fault current for high-reliability power distribution
- Aluminum construction optimized for medium-fault environments with reduced corrosion vs. ferrous metals
- Trefoil clamp geometry secures three-phase cable bundles in 34–38mm diameter range
- Direct cable tray rung mounting with M8 bolt fixing hole—no adapters required
- Natural aluminum finish for visual inspection and compatibility with insulating spacers
- 10-pack configuration supports continuous cable runs and standardized installation
Short circuit faults generate extreme electromechanical forces that can displace unsecured cables, damaging adjacent infrastructure and creating arc flash hazards. The CCALTR3438-X addresses this with a trefoil-specific clamp profile that distributes retention force across three cable contact points, maintaining cable position during fault transients. The aluminum alloy construction provides 121mm of vertical standoff while resisting galvanic corrosion in environments where ferrous cleats would degrade. IEC 61914:2015 certification confirms mechanical retention under standardized fault test conditions, with the 114kA peak rating covering most commercial and light-industrial distribution systems (consult fault study data for installations above 50kA RMS available fault current). The natural aluminum finish allows visual verification of cleat integrity during routine inspections and simplifies identification of corrosion-prone interfaces.
Installation onto standard cable tray uses the integrated M8 fixing hole, which aligns with common tray rung spacing (12" / 300mm nominal). Installers supply grade 8.8 or better M8 bolts and lock washers to meet pull-through resistance requirements—torque to manufacturer-specified values to avoid cleat deformation. When securing aluminum-armored cable, add insulating spacers (sold separately) between the cleat and cable sheath to prevent galvanic cell formation between dissimilar aluminum alloys. The 34–38mm cable diameter range covers common trefoil bundles of 3×150mm² to 3×240mm² conductors; verify actual bundle OD with armor and jacket before ordering. For larger bundles or single-cable runs, reference Panduit's cleat sizing guide to match the correct TR-series model to your cable configuration.
This cleat is engineered for installations requiring documented compliance with IEC 61914 standards, including utility substations, co-generation facilities, and Tier III/IV datacenters with high-capacity UPS and generator distribution. The 10-pack quantity supports typical cable run lengths (one cleat every 1.5–2m per IEC and NEC guidelines) while reducing per-unit cost for large projects. Galvanic corrosion protection via insulating washers is critical in mixed-metal installations—consult NACE SP0169 for material compatibility in your environment.
