Panduit CCAL1H1316-X Aluminum Single-Hole Cable Cleat

The Panduit CCAL1H1316-X is an IEC 61914:2015 certified aluminum cable cleat engineered to retain 13–16 mm diameter cables during short-circuit fault events up to 93.4 kA peak. Designed for low to intermediate fault current environments where corrosion exposure is minimal, this single-hole cleat mounts directly to cable tray rungs using a user-supplied M10 bolt, eliminating the need for separate mounting plates or complex hardware assemblies. The natural aluminum finish delivers a balance of conductivity and weight savings in data center power distribution, battery interconnect runs, and UPS feeder installations where galvanic corrosion risk is controlled through proper material pairing.

Key Features

IEC 61914:2015 certified for short-circuit withstand performance up to 93.4 kA peak fault current

Single-hole mounting design installs directly to cable tray rungs with user-supplied M10 bolt (no adapter plates required)

Aluminum construction provides low-weight solution for less corrosive indoor environments (insulators sold separately to prevent galvanic contact)

Accommodates single cable diameters from 13 mm to 16 mm for common 1 AWG to 2/0 AWG power cables

Natural finish supports visual inspection of contact surfaces and mechanical integrity post-installation

10-piece carton quantity optimizes inventory for mid-scale runs (typical 10–30 meter cable tray segments)

Installation requires a single M10 bolt (not included) torqued per IEC 61914 Annex B guidelines, with the cleat body seated flush against the tray rung to ensure mechanical load transfer during fault events. The 44 mm overall width and 26 mm height provide clearance for adjacent cleats at 150–200 mm spacing intervals, meeting typical utility and NEC 110.14(D) working space requirements when installed on 150 mm wide ladder tray. Panduit specifies insulating washers and spacers (sold separately, see CCAL-W and CCAL-S families) when mounting aluminum cleats to steel or stainless tray to prevent galvanic corrosion in humid or coastal environments. The cleat's open-top geometry allows visual verification of cable seating without disassembly, critical for commissioning inspections and thermal imaging surveys.

This cleat is specified in battery string interconnect applications where multi-ton short-circuit forces must be contained within the tray system rather than transferred to equipment terminals. Data centers running 380 VDC or 400 VDC distribution buses use IEC 61914 cleats as a mechanical backstop to cable ties, preventing ejection during inverter faults or parallel UPS backfeed events. The aluminum alloy composition resists work-hardening during thermal cycling (−40°C to +90°C service range per IEC 61914 Clause 6.2), maintaining clamp force across seasonal temperature swings in unconditioned telecom shelters and outdoor battery enclosures. Installers working under NFPA 70 Article 480 (battery installations) or IEC 62040-1 (UPS systems) cite the single-hole design for faster rough-in compared to two-hole variants, reducing labor hours on runs exceeding 50 cleats per string.

IEC 61914:2015 certification requires third-party witnessed testing of fault current withstand (electromagnetic forces), temperature rise (I²t heating), and mechanical endurance (vibration/impact). The CCAL1H1316-X test report validates performance at 93.4 kA peak (approximately 40 kA RMS symmetrical at power factor 0.7), positioning this cleat for industrial facilities with 480Y/277V or 400Y/230V services backed by 1500–2500 kVA transformers. Competitive cable ties and Velcro wraps lack short-circuit test data entirely; this cleat provides engineered justification for AHJ approval and insurance underwriter review in mission-critical power projects where a single cable failure could propagate across an entire DC bus.
