Panduit CCALTR6675-X Aluminum Trefoil Cable Cleat

The Panduit CCALTR6675-X is an aluminum trefoil cable cleat engineered for medium to high short circuit fault protection in commercial power distribution and industrial electrical installations. Certified to IEC 61914:2015 and tested to 114kA peak fault current, this cleat retains cables during fault events to prevent whip and subsequent damage to adjacent infrastructure. Designed for trefoil-configured cables with 66-75mm outer diameter, the aluminum construction offers durability in less corrosive environments while maintaining compliance with international cable retention standards. Sold in 10-packs for cost-effective deployment across multi-run installations.

Key Features

• Compatible with separately sold insulating spacers and washers to prevent galvanic corrosion between dissimilar metals

IEC 61914:2015 is the international standard governing cable cleats used to secure electrical cables against the electromechanical forces generated during short circuit faults. The CCALTR6675-X meets this standard with a peak fault current rating of 114kA—sufficient for medium-voltage and high-current industrial applications where fault energy can exceed 50kA. Aluminum construction reduces weight compared to stainless steel alternatives while maintaining mechanical strength, making it suitable for installations where corrosive exposure is limited (indoor substations, data center power distribution, commercial electrical rooms). The trefoil configuration is critical for three-phase power systems where cables are arranged in triangular proximity to minimize magnetic field interaction. At 66-75mm cable diameter, this cleat accommodates large-gauge conductors commonly found in 480V, 600V, and medium-voltage distribution circuits. Aluminum's natural oxide layer provides baseline corrosion resistance, but installations involving dissimilar metals (steel cable trays, copper conductors) require insulating washers and spacers (sold separately) to prevent galvanic cells that accelerate corrosion.

Installation is straightforward: the cleat mounts directly to cable tray rungs via the integrated fixing holes using user-supplied M8 bolts, eliminating the need for custom brackets or rail adapters. This direct-mount approach accelerates deployment in retrofit scenarios where existing cable tray infrastructure already supports the cable runs. The 193mm height provides adequate clearance above the tray surface for large-diameter cables without interference from adjacent tray levels or overhead conduit. Trefoil cleats are typically spaced at regular intervals along the cable run per IEC 61914 guidelines—spacing depends on fault current magnitude, cable diameter, and installation environment. For installations exceeding 50kA prospective fault current, closer spacing (often 0.5-1.0 meter intervals) is required to prevent cable movement during fault events. The 10-pack quantity is sized for a typical single-run installation spanning 5-10 meters, depending on required spacing. Integrators should calculate cleat spacing using manufacturer-provided fault withstand tables or the Panduit cleat calculator tool (reference installation guide) to ensure compliance with local electrical codes and IEC standards.

This cleat is specified in commercial and industrial power distribution projects where code compliance, fault protection, and long-term reliability intersect. Common applications include data center busway-to-transformer runs, industrial substation feeder circuits, hospital emergency power distribution, and commercial building service entrance installations. The IEC 61914:2015 certification satisfies Authority Having Jurisdiction (AHJ) requirements in most jurisdictions, streamlining inspection and approval processes. Aluminum construction aligns with NFPA 70 (National Electrical Code) guidelines for cable support systems while reducing installed weight compared to steel alternatives. For marine, chemical processing, or high-humidity environments, consider stainless steel variants. Insulating spacers and washers (Panduit part numbers sold separately) are mandatory when mounting to steel cable tray to prevent galvanic corrosion and ensure the cleat's rated service life.
