Panduit CCSSTR4652-X 46-52mm Trefoil Cable Cleat

Panduit CCSSTR4652-X Trefoil Cable Cleat

The Panduit CCSSTR4652-X is a Type 316L stainless steel trefoil cable cleat engineered for three-phase power distribution in harsh industrial environments and critical infrastructure installations. Certified to IEC 61914:2015 and tested to withstand fault currents up to 172kA, this cleat prevents cable movement and electromagnetic repulsion forces during short-circuit events—protecting both personnel and equipment in datacenters, substations, utility vaults, and process facilities. Designed for 46–52mm diameter trefoil cable bundles, it ships in 10-packs with removable stainless spacers and accepts user-supplied M8 mounting hardware for direct installation to cable tray rungs or via mounting brackets.

Key Features

• IEC 61914:2015 certified, tested to 172kA maximum fault current
• Type 316L stainless steel construction for marine, chemical, and outdoor applications
• Trefoil configuration secures three-phase cable bundles in touching formation
• Accepts 46–52mm diameter cables with removable spacer for fit adjustment
• Dual mounting: direct to cable tray via M8 bolt or bracket-mount
• 10-pack quantity for multi-run installations

Short-circuit fault currents generate massive electromagnetic forces that can dislodge unsecured cables, causing phase-to-phase contact, insulation failure, or arc flash escalation. The CCSSTR4652-X cleat mechanically restrains cables during the first half-cycle of a fault event, before protective relays can isolate the circuit. Its trefoil saddle geometry matches the natural triangular packing of three single-core cables, distributing clamping pressure evenly and maintaining the 120° phase spacing that minimizes inductance and magnetic force imbalance. The 316L stainless body resists pitting and crevice corrosion in chloride-rich coastal environments, chemical plants, wastewater facilities, and scrubber exhaust areas where standard 304 stainless or aluminum cleats degrade. The removable spacer lets you fine-tune fit across the 46–52mm cable range without stocking multiple cleat sizes—critical when cable OD varies due to insulation type, armor, or manufacturing tolerance.

Installation follows two paths: for ladder or mesh cable tray, thread a user-supplied M8 × 20mm bolt through the integral mounting hole and the tray rung, then torque per Panduit's installation guide (typically 10–12 N·m). For wall, beam, or unistrut mounting, use Panduit's compatible mounting brackets (sold separately) which provide standoff and adjust for uneven surfaces. Cleat spacing depends on cable size, tray span, and fault-level calculation per IEC 61914 Annex B—typical spacing ranges from 300mm to 1200mm for 46–52mm trefoil runs at 50kA prospective fault current. Each cleat weighs approximately 0.4kg and presents a 117mm overall height when installed, so verify vertical clearance in congested tray stacks. The natural mill finish provides corrosion resistance without coatings that can chip or flake in high-vibration or thermal-cycling environments.

This product meets IEC 61914:2015 Type Testing requirements, meaning representative samples were subjected to the specified fault current in a certified test lab and demonstrated no structural failure, no cable ejection, and no permanent deformation beyond allowable limits. Competitive alternatives from Thomas & Betts (379TC07), Ellis Patents (ER44-50), and others may use different base materials or test standards—verify that third-party cleats carry IEC 61914 certification and that the tested fault current matches or exceeds your site's calculated prospective fault level. The CCSSTR4652-X is stocked for immediate shipment and pairs with Panduit's trefoil cleats in adjacent size ranges (CCSSTR4046-X for 40–46mm, CCSSTR5258-X for 52–58mm) to support mixed cable schedules across a single project.
