Panduit A2-56RF-C 2 AWG Compression Lug — 90° Right-Angle Termination

The Panduit A2-56RF-C is a tin-plated copper compression lug designed for heavy-duty battery and power distribution terminations in UPS systems, backup power installations, and industrial control panels. Built for 2 AWG conductors with a 90-degree right-angle bend and 5/16-inch stud, this lug delivers reliable, corrosion-resistant connections in environments where space constraints demand compact terminations and regulatory compliance is non-negotiable.

Key Features

• 2 AWG conductor capacity with 5/16" stud hole for secure post-style terminations
• 90° right-angle bend positions cable parallel to mounting surface, saving enclosure depth
• Tin-plated copper barrel meets ASTM Class C corrosion resistance for UPS and battery room environments
• cULus Listed to UL 486A-486B for power applications in the US and Canada
• Meets US Military pull-out strength specifications when crimped with Panduit-recommended tooling
• Standard sealed barrel (no inspection window) prevents contamination in dusty or outdoor installations
• Flared barrel entry simplifies insertion of stranded flex conductors during field terminations
• 100-piece contractor pack reduces per-termination cost on multi-rack UPS deployments

Battery bank and UPS terminations demand lugs that won't corrode under thermal cycling or fail under fault-current pullout forces. The A2-56RF-C's tin plating protects against galvanic corrosion when mated to aluminum bus bars or dissimilar metals, a common issue in telecom and datacenter backup power systems. The sealed barrel design keeps moisture and particulates out of the crimp zone—critical in mechanical rooms or outdoor generator transfer switch enclosures where airborne contaminants accelerate connection degradation.

The 90-degree bend is purpose-built for tight enclosures: when terminating battery strings in 2-post racks or shallow ATS cabinets, the right-angle orientation routes cable flat against the back plane instead of projecting into service clearance zones. This orientation also reduces stress on the crimp when cables are bundled or secured to vertical risers, since the bend distributes flexural load across the barrel rather than concentrating it at the crimp interface.

The flared barrel entry is a field-install detail that matters during high-volume deployments. When you're terminating 40+ battery leads in a multi-string UPS installation, a chamfered entry cuts prep time and reduces the risk of frayed strands that compromise crimp integrity. Paired with a Panduit hydraulic compression tool (not included), the A2-56RF-C achieves repeatable, code-compliant crimps that meet both UL 486 and military MIL-DTL pull-out specs—eliminating the guesswork of inspection and ensuring every termination passes AHJ review without rework.

cULus dual-certification to UL 486A-486B covers both aluminum and copper conductor terminations, making this lug a compliant choice for mixed-metal battery and feeder installations across North America. The 100-piece pack reduces packaging waste and per-lug cost on projects with dozens of identical terminations—common in modular UPS systems, solar combiner boxes, and industrial DC distribution panels. Tin plating remains stable across temperature extremes typical of uncontrolled mechanical spaces, maintaining low contact resistance over decades of thermal cycling.
