Panduit CCALTR4044-X Aluminum Trefoil Cable Cleat
The Panduit CCALTR4044-X cable cleat provides IEC 61914:2015-certified short circuit protection for trefoil cable configurations in medium to high fault current environments. Designed for 40-44mm diameter cables, this aluminum cleat is tested to withstand peak fault currents up to 114kA, retaining cables during short circuit events that would otherwise cause catastrophic cable whip and infrastructure damage. The trefoil geometry secures three-cable groupings in the close-spaced triangular formation typical of three-phase power distribution, making it essential for data center feeders, industrial substations, and utility-grade installations where fault current protection is mandated.

IEC 61914:2015 is the global standard for cable cleats used in short circuit protection, defining mechanical testing protocols that simulate the electromagnetic forces generated during fault events. The CCALTR4044-X's 114kA rating places it in the heavy-duty category suitable for industrial and utility applications where available fault current can exceed 50kA. During a short circuit, electromagnetic forces between parallel conductors can generate thousands of pounds of lateral force in milliseconds; without proper retention, cables can separate from supports, contact adjacent phases, or strike personnel and equipment. Trefoil geometry—where three conductors are arranged in a tight triangular pattern—reduces magnetic field asymmetry and balances forces across the cable bundle, but requires a cleat specifically designed to cradle all three conductors in that configuration. The CCALTR4044-X's formed aluminum saddle holds the trefoil formation while the TR clamp mechanism secures the bundle against movement.
Aluminum construction offers corrosion resistance superior to steel in many environments, particularly where moisture or chemical exposure is present but chloride levels remain moderate. The natural finish provides a balance between cost and environmental durability. When mounting to galvanized or stainless steel cable tray, however, direct aluminum-to-steel contact creates galvanic cells that accelerate corrosion in the presence of an electrolyte (condensation, wash-down water, etc.). Panduit recommends installing insulating spacers and washers (sold separately) between the cleat and tray to eliminate metal-to-metal contact and prevent galvanic degradation. The cleat mounts directly to the cable tray rung via its integral fixing hole using a user-supplied M8 bolt, eliminating the need for separate brackets or adapters. Spacing between cleats should follow IEC 61914:2015 guidance and cable manufacturer recommendations, typically every 600-900mm for horizontal runs and closer intervals for vertical or unsupported spans.
The 10-pack configuration aligns with typical project procurement—data center row feeders, industrial panel feeds, and substation bus duct terminations often require multiple cleats per cable run, and the bulk packaging reduces per-unit cost and simplifies inventory management. Compliance with IEC 61914:2015 satisfies NEC 110.14, Canadian Electrical Code Part I, and international standards that reference IEC fault current protection requirements, making the CCALTR4044-X a globally applicable solution for medium-voltage and high-current low-voltage installations where short circuit retention is a design, insurance, or regulatory mandate.
