Panduit A3/0-38R-C Pan-Lug™ Battery Cable Lug

The Panduit A3/0-38R-C is a heavy-duty copper compression lug engineered for high-current battery and power distribution systems in UPS installations, datacenter battery banks, and commercial backup power applications. Designed for 3/0 AWG conductors and 3/8-inch studs, this tin-plated lug delivers corrosion-resistant, code-compliant terminations that meet both UL 486A-486B standards and military pullout strength requirements. Sold in 100-piece packages, the A3/0-38R-C gives integrators a cost-effective solution for large-scale battery room builds and power infrastructure projects.

Flared barrel entry simplifies insertion of stranded conductors during crimping

cULus Listed to UL 486A-486B for power applications in the US and Canada

Meets US Military wire pullout specifications when used with Panduit-recommended crimping tools

Embossed wire size marking for quick verification during installation and inspection

100-piece package quantity for multi-string battery installations and large projects

Panduit engineers the A3/0-38R-C with high-conductivity copper and a tin-plated finish that meets ASTM Class C corrosion-resistance specifications—critical for battery room environments where sulfuric acid vapor and moisture accelerate oxidation. The sealed barrel design eliminates the inspection window found on some competing lugs, preventing water and contaminants from migrating into the crimp area over the 10-15 year lifespan of a typical battery bank. The flared barrel entry guides stranded 3/0 AWG flex cable into the compression zone without snagging individual strands, reducing prep time and ensuring consistent crimp quality across hundreds of terminations. Each lug is embossed with the wire size, eliminating guesswork during QA walkthroughs and making it easy for inspectors to verify correct sizing without referring to cut sheets.

Use the A3/0-38R-C for negative and positive bus connections in battery strings rated from 125 VDC to 250 VDC, common in large UPS systems supporting datacenter critical loads or hospital emergency power. The 3/8" stud hole fits standard battery terminal posts and distribution bus bars without requiring adapters or oversized hardware. The lug's high pullout strength—validated to military specs when crimped with Panduit MD6-360 or equivalent dies—ensures reliable connections in seismic zones and high-vibration telecom shelter environments. The 100-count packaging aligns with typical battery room builds: a 40-battery UPS string requires 80 lugs (positive and negative on each cell), so one carton covers a full string with spares for future replacements or expansions. This lug is also suited for solar inverter DC input terminations, large-format energy storage systems, and industrial DC distribution panels where code requires listed components and long-term reliability.

The A3/0-38R-C carries cULus Listing under UL 486A-486B, the governing standard for wire connectors in power circuits, ensuring compliance with NEC Article 110.3(B) and Canadian Electrical Code Part I. This listing covers both aluminum and copper conductors, though the tin-plated copper barrel is optimized for copper flex cable commonly specified in battery interconnects. When paired with Panduit's crimping tools and following the manufacturer's installation instructions, these lugs meet the mechanical and electrical performance criteria required by most US jurisdictions, including California Title 24 energy storage installations and OSHPD seismic ancillary component approvals. For integrators working on design-build UPS projects or retrofitting aging battery banks, the A3/0-38R-C provides a field-proven, inspector-accepted termination solution that balances cost, performance, and long-term durability in mission-critical power infrastructure.
