Panduit CCALTR2528-X Aluminum Trefoil Cable Cleat, 25–28mm, Pack of 10

Overview

The Panduit CCALTR2528-X is an aluminum trefoil cable cleat engineered to retain and restrain three-conductor trefoil cable bundles — 25 to 28mm in diameter — under medium-to-high fault current conditions. Certified to IEC 61914:2015 and tested to withstand up to 114kA peak fault current, this cleat is designed for electrical installation environments where cable containment under short-circuit forces is a code-compliance and safety requirement, not an afterthought. The CCALTR2528-X (often searched as CCALTR2528 X) ships as a pack of 10 units, appropriate for run-length electrical panel, switchgear room, and cable ladder installations where repeating cleat spacing is specified by the design engineer.

Aluminum construction makes this cleat the right call for environments that are less corrosive — typical indoor switchgear and cable ladder rooms — where the weight savings and machinability of aluminum are advantages over steel, but where galvanic corrosion risk is managed by design. Panduit supplies spacers and washers separately, specifically because protecting aluminum-to-steel contact points from galvanic corrosion requires hardware selected to match the installation substrate. Plan your BOM accordingly.

Key Features

• IEC 61914:2015 Certification: This is not a self-declared rating — IEC 61914 is the international standard governing cable cleats, covering mechanical strength, fault-current retention, and environmental performance. Specifying a certified cleat on cable ladder runs keeps the installation auditable and defensible during commissioning and insurance review.
• 114kA Peak Fault Current Rating: Tested to retain cables at 114kA maximum fault current. For medium-voltage distribution and high-capacity LV installations where a bolted fault could generate extreme electromagnetic forces, this rating tells you whether the cleat will hold the cable bundle in place or allow conductor whip — a life-safety distinction.
• Trefoil Configuration: Designed specifically for three-conductor cables arranged in a trefoil pattern (equilateral triangle cross-section). This geometry minimizes skin effect and proximity losses in AC power cable runs. The cleat maintains the trefoil arrangement under both normal operation and fault conditions — substituting a flat formation cleat here would compromise both electrical performance and fault retention geometry.
• 25–28mm Cable Diameter Range: The cleat is sized for cables with outer diameters between 25 and 28mm. Measure your cable OD before ordering — cable cleats are not adjustable, and an incorrect size means the cleat either won't close properly or won't grip the cable under fault load. Competitor cross-references for this size range include 376AB02, 376AC02, ALP02-AN0, ALP02-AN1, LDAL023028, and SDAL023028.
• Cable Ladder Tray Compatibility: Installs directly into the fixing hole of a cable ladder rung. Hardware required: M8 bolt (not included). This is a standard metric fastener available from any electrical hardware supplier — no proprietary fixings needed, which simplifies procurement on multi-vendor installations.
• Aluminum Construction — Natural Finish: The natural aluminum finish (no anodizing or coating) keeps cost down in dry indoor environments. If galvanic corrosion is a concern where the cleat contacts dissimilar metals, Panduit-specified spacers and washers are available separately and should be specified in the BOM from the outset rather than retrofitted.
• Pack of 10: At 103mm overall height per unit, these are not small components. The 10-pack quantity aligns with run-length installations where the structural engineer's cable cleat spacing schedule typically calls for repeating intervals. Ordering by the pack reduces per-unit cost and ensures consistent cleat generations across a run.

Integration & Compatibility

The CCALTR2528-X installs on Panduit and compatible cable ladder systems at rung fixing holes using a standard M8 bolt (not included in the pack). It is specifically designed for trefoil cable configurations — three single-core cables in triangular arrangement — common in three-phase medium and low voltage power distribution runs. Spacers and washers for galvanic corrosion isolation are sold separately by Panduit and should be specified when the cable ladder substrate is steel or another dissimilar metal. Cross-reference to competitor part numbers 376AB02, 376AC02, ALP02-AN0, ALP02-AN1, LDAL023028, and SDAL023028 for replacement or specification matching purposes.

If you are planning a cable ladder installation, also consider cable tray systems and associated cable management accessories for a complete routed system.

Frequently Asked Questions

Q: What cable outer diameter does the CCALTR2528-X fit?

A: The CCALTR2528-X is rated for cables with an outer diameter of 25 to 28mm. Measure your cable OD before ordering — this cleat is not adjustable. Using the wrong size will compromise grip and fault retention performance.

Q: What fault current rating has the CCALTR2528-X been tested to?

A: The CCALTR2528-X has been tested to a maximum fault current of 114kA peak, in accordance with IEC 61914:2015. This is a medium-to-high fault current rating suitable for demanding LV and MV cable ladder installations.

Q: Is the M8 mounting bolt included with the CCALTR2528-X?

A: No. The M8 bolt required to mount the cleat into a cable ladder rung fixing hole is not included. It is a standard metric fastener available through electrical hardware suppliers. Spacers and washers for galvanic corrosion protection are also sold separately by Panduit.

Q: What standard does the CCALTR2528-X comply with?

A: The CCALTR2528-X is certified to IEC 61914:2015, the international standard for cable cleats covering mechanical performance, fault-current retention, and environmental requirements.

Q: Can the CCALTR2528-X be used in highly corrosive environments?

A: No. Panduit specifies this cleat for less corrosive environments. The natural aluminum construction without additional protective coating limits suitability in aggressive chemical or high-humidity environments. For corrosive environments, evaluate stainless steel cleat variants. When installed on steel cable ladders, use the separately sold Panduit spacers and washers to mitigate galvanic corrosion at contact points.

Q: How many cleats are included per order?

A: Each order of the CCALTR2528-X includes 10 aluminum trefoil cable cleats.

James Everett

The CCALTR2528-X is one of those components that gets specified on paper and then forgotten until commissioning — and that is exactly when an under-rated or wrong-size cleat becomes a problem. The 114kA peak fault current test rating under IEC 61914:2015 is the number that matters here: it tells you this cleat was physically tested at that level, not just assigned a rating by the manufacturer. For medium-voltage or high-capacity LV installations where a fault event could generate violent electromagnetic forces on the cable bundle, that test pedigree is the difference between a held installation and a whipped conductor.

Technical Highlights:

• 114kA Fault Current Test: Verified by IEC 61914:2015 test protocol — not a self-declared rating. Ensures the cleat retains cable bundle geometry under worst-case short-circuit forces in medium-to-high fault current environments.
• 25–28mm OD Range: Precisely sized for this cable OD band. Trefoil cleat geometry cannot compensate for an oversize or undersize cable — correct OD matching is essential for the cleat to apply the correct retention force under fault load.
• Aluminum / Natural Finish: Lighter than steel, no coating degradation in dry indoor environments. The tradeoff is galvanic corrosion risk at dissimilar-metal interfaces — Panduit sells the spacers and washers to manage this, but they are not in the box and must be specified separately.

Deployment Considerations:

• Specify the M8 bolt and Panduit spacers/washers in the same purchase order as the CCALTR2528-X — arriving on-site without them adds an installation delay that is entirely avoidable.
• Aluminum is the right material choice for dry indoor switchgear rooms and cable risers; it is the wrong choice for outdoor cable trays, process plant environments, or any location with chloride exposure. If the environment is in question, default to a stainless steel variant rather than relying on spacers alone.

The CCALTR2528-X is a strong specification choice for indoor LV/MV cable ladder runs in switchgear rooms, sub-station cable risers, or industrial panel installations where IEC 61914:2015 certification is a project requirement and the cable bundle OD falls in the 25–28mm range.
