Panduit A2-12R-C 2 AWG 1/2" Stud Compression Lug

The Panduit A2-12R-C Pan-Lug™ compression lug delivers reliable, code-compliant termination for 2 AWG battery cable and power distribution applications. Designed for 1/2" stud connections, this tin-plated copper lug is engineered for the high-current, high-vibration environments found in UPS systems, emergency power installations, and critical infrastructure battery banks. Supplied in 100-piece packages, the A2-12R-C provides the consistency and performance commercial integrators need when terminating battery strings, generator tie-ins, or DC distribution panels.

Key Features

2 AWG wire capacity with 1/2" stud size for heavy-duty battery and UPS connections

Tin-plated copper construction resists corrosion and ensures low-resistance contact over decades of service

Flared entry design guides wire insertion and reduces installation time in tight enclosures

Embossed wire size markings eliminate guesswork during termination and inspection

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

Meets US Military Wire Pull Out Specifications for high-vibration and mission-critical installations

100-piece package quantity supports multi-string battery installations and standardized inventories

The A2-12R-C uses high-conductivity copper barrel and tongue construction, tin-plated to resist oxidation in battery room environments where sulfation, humidity, and temperature cycling are constant threats. The flared entry on the barrel provides a generous lead-in that accommodates stranded 2 AWG conductors without pre-fanning, reducing prep time when terminating dozens of battery interconnects in a single installation. The embossed wire size on the barrel face ensures that inspectors and service techs can verify proper sizing without referencing prints or labels, a requirement on many AHJ inspections and UL 924 emergency power system validations.

Compression termination provides superior pullout strength compared to mechanical set-screw lugs, a critical factor in seismic zones or mobile power applications where vibration can loosen threaded connections over time. The A2-12R-C is designed for use with standard hex compression tools, creating a cold-weld bond between lug and conductor that meets US Military pull-out specs. This makes the A2-12R-C the preferred choice for battery strings feeding critical infrastructure—telecom CO battery plants, hospital UPS systems, data center 48VDC distribution, and solar + storage installations where a single failed termination can take down an entire branch.

cULus Listed to UL 486A-486B and compliant with US Military Wire Pull Out Specifications, the Panduit A2-12R-C compression lug is engineered for integrators who can't afford callbacks on power terminations. Whether you're landing battery leads on inverter terminals, building DC distribution busbars, or terminating generator neutral-ground bonds, the A2-12R-C delivers the mechanical and electrical performance the job demands.
