Panduit A2-38RF-C 2 AWG 90° Battery Cable Lug

Panduit A2-38RF-C 2 AWG 90° Battery Cable Compression Lug

The Panduit A2-38RF-C is a professional-grade compression lug engineered for terminating 2 AWG battery cables to 3/8" studs in backup power systems, UPS installations, and data center environments. The 90° barrel orientation keeps cable bend radius tight in dense equipment racks while the tin-plated copper construction meets ASTM Class C corrosion resistance for harsh environments. Each lug features a closed barrel design without inspection windows to prevent contamination ingress—critical for outdoor telecom cabinets and industrial battery banks. Manufactured to cULus standards and tested to military pullout specifications, this 100-pack delivers the mechanical strength and long-term reliability integrators need for mission-critical power infrastructure.

Key Features

• 2 AWG wire capacity with 3/8" stud hole for standard battery terminal posts
• 90° barrel angle reduces cable bend stress in tight rack-mount installations
• Tin-plated copper construction resists corrosion in outdoor and high-humidity environments
• Closed barrel without inspection window prevents dust and moisture contamination
• Flared barrel entry eases insertion of stranded flex conductors during field termination
• Exceeds military pullout strength requirements when crimped with Panduit tooling
• cULus Listed to UL 486A-486B for power applications in US and Canada
• 100-piece pack supports multi-battery UPS arrays and large telecom deployments

The A2-38RF-C uses high-conductivity copper with ASTM Class C tin plating—a thicker, more durable coating than standard commercial tin finishes. This plating protects the base metal from sulfation and oxidation in battery rooms where acid vapor exposure is constant. The 90° barrel orientation is purpose-built for applications where cable routing must stay parallel to the equipment face: front-access UPS battery cabinets, telco battery strings in 23-inch relay racks, and solar inverter DC terminations. The closed barrel design eliminates the inspection window found in cheaper lugs—Panduit engineering found that window cutouts create stress concentration points and entry paths for conductive debris in outdoor environments. The flared barrel entry is sized for 2 AWG Class B and Class C stranded conductors, accommodating both fine-strand welding cable and coarser building wire.

Battery-backed systems demand terminations that won't degrade over 15–20 year service lives. Integrators installing solar+storage systems, telecom BDFB (Battery Distribution Fuse Bay) arrays, and data center 480V DC plants rely on the A2-38RF-C's military-spec pullout strength to survive seismic events, thermal cycling, and mechanical vibration. The 100-pack quantity matches common deployment scales: a 40-battery UPS string requires 80 lugs (positive and negative per battery), leaving spares for future expansions. The tin plating maintains low contact resistance (<5 microhms) across temperature swings from -40°C to +90°C—crucial for maintaining charge efficiency in unheated telecom shelters and desert solar farms.

Panduit specifies hydraulic compression tooling for the A2-38RF-C to achieve the pullout strengths listed in MIL-DTL-20459—typically 1,200+ pounds for 2 AWG. Manual ratchet crimpers will seat the lug but may not meet the military spec. The flared entry helps field crews start the conductor into the barrel without fraying strands, even when working overhead in battery racks. Once crimped, the seamless barrel distributes compression force evenly around the conductor, eliminating the cold-flow and strand breakage common with bolted lugs. For projects requiring traced calibration (government, utility, critical infrastructure), Panduit provides crimp tool die certification and batch traceability documentation.

The A2-38RF-C meets cULus requirements under UL 486A (wire connectors) and UL 486B (splicing connectors), ensuring NEC and CEC code compliance for battery terminations in the US and Canada. The tin plating exceeds the corrosion resistance needed for outdoor telecom cabinets (NEBS GR-487) and marine environments where salt fog accelerates oxidation. Panduit's Pan-Lug family has been the standard in telecom central offices and data centers for decades because they don't fail in the field—vibration from chillers, thermal cycling from load swings, and 20-year battery service intervals don't cause the contact degradation or pullout seen with inferior connectors. For integrators building power infrastructure that must outlast the initial equipment, the A2-38RF-C delivers proven reliability at a per-termination cost that's negligible compared to a single service call for a failed connection.
