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.
