Panduit A2/0-12R-C 2/0 AWG 1/2" Stud Battery Cable Lug

Heavy-duty battery and UPS installations demand terminations that won't fail under load, vibration, or time. The Panduit A2/0-12R-C Pan-Lug compression lug handles 2/0 AWG conductors on 1/2" studs with the pull-out strength and corrosion resistance critical for backup power systems in datacenters, telecom facilities, and critical infrastructure. Tin-plated high-conductivity copper construction meets cULus requirements for power applications, while embossed wire-size markings and flared entry speed installation across large battery banks.

Key Features

2/0 AWG wire capacity with 1/2" stud — direct fit for common battery terminals and busswork

Flared barrel entry guides stranded conductors without fraying, reducing prep time and rejected crimps

Tin-plated copper body resists oxidation in humid or coastal environments where UPS rooms run warm

Embossed wire size on each lug eliminates guesswork during pull-from-the-box installation

High pull-out strength tested to US Military specs — holds under vibration and thermal cycling

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

100-piece packaging supports battery-bank builds without mid-job reorders

The A2/0-12R-C uses Panduit's compression-barrel design — no set screws, no split bolts, just a hex crimp that delivers 360° contact and gas-tight termination. The flared entry accepts stranded 2/0 cable without pre-shaping, a real advantage when you're working in tight UPS cabinets or retrofit battery enclosures. Tin plating over copper keeps contact resistance low even after years in service, and the embossed size marking (printed on every lug) means installers can verify wire-to-lug match without calipers or reference cards.

Battery cable terminations see sustained DC loads, infrequent but massive inrush currents during transfer, and slow thermal cycling as ambient temperatures shift. Standard automotive or light-duty lugs can cold-flow, oxidize, or pull loose over 5–10 year service intervals. The A2/0-12R-C is engineered for stationary power: thick copper barrel, full-length crimp zone, and compliance with UL 486A-486B pull-out and temperature-rise tests. It's the lug you install once and forget, which is exactly what long-life UPS and battery-bank applications require.

Supplied in 100-piece packages, the A2/0-12R-C covers typical datacenter UPS builds (48V or 480V battery strings with 10–40 termination points per bank) without excess inventory. Pair with Panduit CT-series compression tools for consistent crimp force, or use standard hex dies if you already have a hydraulic crimper in the truck. The 1/2" stud size matches most UPS battery terminals, DC distribution blocks, and inverter input lugs — verify your specific hardware, but this is the default size for 2/0 cable in stationary power work.

cULus Listed for use in the US and Canada, tested to UL 486A-486B power-connector standards, and built to meet US Military wire pull-out specifications. Panduit Pan-Lug compression terminations deliver field-proven reliability for installations where downtime costs thousands per minute and battery backup is the last line of defense.
