Panduit A2-56R-C 2 AWG 5/16" Compression Lug

The Panduit A2-56R-C Pan-Lug compression terminal delivers field-proven reliability for 2 AWG battery banks, UPS installations, and DC power distribution in commercial security and datacenter environments. Tin-plated copper barrel with 5/16" stud hole, supplied in contractor-friendly 100-piece packs. cULus Listed to UL 486A-486B for power applications and qualified to US Military wire pull-out specifications—engineered for integrators who stake uptime on every crimp.

Key Features

2 AWG wire capacity with 5/16" stud mounting—direct fit for battery terminals, bus bars, and grounding points in access control and surveillance power systems

Tin-plated copper construction resists corrosion in telecoms closets, outdoor equipment shelters, and high-humidity environments

Flared barrel entry and embossed wire-size marking speed field installation and reduce mis-crimps during multi-circuit runs

cULus Listed for US and Canada installations per UL 486A-486B; meets MIL-STD pull-out strength for mission-critical DC distribution

100-piece contractor pack eliminates mid-job reorders on large battery-backup deployments and multi-building campus projects

Commercial integrators installing distributed battery systems for IP camera networks, access control panels, and fire-alarm circuits rely on compression lugs that survive decades in the field without thermal creep or oxidation failures. The A2-56R-C's tin-plated barrel maintains low contact resistance across temperature swings and humidity cycles common in equipment rooms and outdoor NEMA enclosures. Flared wire entry accepts stranded 2 AWG conductors without fraying, and the embossed size marking prevents wire-gauge errors during parallel runs—critical when a single battery bank feeds multiple security subsystems.

The 5/16" stud hole mates cleanly with standard battery posts, grounding lugs, and bus-bar hardware across UPS brands. Panduit's 1.89" overall length provides clearance in tight battery compartments while keeping the crimp zone accessible for hydraulic and mechanical tooling. Every lug in the 100-pack meets the same pull-out spec that governs military power distribution—proof-tested insurance against call-backs from loose connections in always-on surveillance infrastructure.

cULus dual-listing to UL 486A-486B covers both aluminum and copper conductors in power applications, ensuring inspector acceptance on commercial jobs. Compliance with US Military wire pull-out specifications provides the pull-strength margin integrators need when routing 2 AWG home runs through conduit bends or securing feeders to vibration-prone rack-mount UPS units. For mission-critical installs where a failed battery connection means lost footage or a dark access gate, the A2-56R-C is the lug senior integrators spec by part number.
