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

Panduit A2-56RH-C 2 AWG Compression Lug for Battery and UPS Power Terminations

The Panduit A2-56RH-C compression lug delivers reliable, code-compliant wire terminations for battery backup systems, UPS installations, and DC power distribution in surveillance and datacenter environments. Designed for 2 AWG conductors and 5/16" studs, this tin-plated copper lug handles the high-current connections that keep NVRs, access control panels, and critical security infrastructure running during power events. The 45-degree angle clears tight enclosure walls and terminal blocks, while the flared barrel speeds up stripping and insertion on flexible battery cable. Sold in 100-piece contractor packs for multi-rack installations where a single failed crimp can take down an entire security zone.

Key Features

• Tin-plated copper construction meets ASTM Class C corrosion resistance for long-term reliability in battery rooms and outdoor enclosures
• 2 AWG wire capacity with 5/16" stud connection for direct attachment to battery posts, UPS terminals, and power distribution blocks
• 45-degree angle clears enclosure walls and adjacent terminals in tight rack-mount UPS and battery backup installations
• Flared barrel entry guides stranded and flexible conductors into the crimp zone without fraying or strand breakage
• High pullout strength exceeds military wire termination specifications when crimped with Panduit-recommended tooling
• Closed barrel without inspection window prevents dust, moisture, and corrosive gases from entering the crimp interface
• cULus Listed to UL 486A-486B for power applications in the United States and Canada
• 100-piece bulk packaging reduces per-termination cost on large surveillance installations with multiple battery strings

Panduit designed the A2-56RH-C with a closed-barrel geometry that locks out contaminants while maintaining full contact around the conductor bundle. The tin plating provides a solderable surface and guards against the galvanic corrosion that occurs when dissimilar metals meet in humid or coastal environments. The 45-degree offset positions the barrel parallel to enclosure walls when the stud mounts perpendicular, eliminating the clearance fights common with straight lugs in shallow junction boxes or crowded battery cabinets. The flared entry chamfer lets installers seat flex cable without pre-forming or strand cleanup, cutting prep time on each termination and reducing scrap from damaged conductors.

In surveillance and access control deployments, these lugs terminate the DC feeders between battery banks and UPS inverters, the jumpers between series-connected 12V batteries in extended-runtime enclosures, and the positive/negative mains feeding remote power supplies for PTZ cameras and door strikes. Proper crimps matter: a cold joint at a battery lug creates resistance, generates heat under load, and can carbonize insulation or melt terminal blocks during a generator-transfer event or a long utility outage. The A2-56RH-C's high pullout strength keeps conductors seated through the thermal cycling and vibration common in rooftop equipment shelters and mechanical-room UPS racks. For integrators running strings of four to twelve batteries per NVR or access panel, the 100-count packaging covers an entire installation without mid-job reorders.

Compliant with UL 486A-486B for aluminum and copper conductors in power wiring, and cULus Listed for use in both US and Canadian electrical installations. Meets US Military pullout strength specifications when terminated with Panduit CT-series compression tools and appropriate dies. The closed-barrel design qualifies for installations in NEMA-rated enclosures and outdoor battery cabinets where open-inspection-window lugs would admit moisture or salt spray. For commercial integrators spec'ing battery backup on surveillance projects, datacenter UPS expansions, or access control power distribution upgrades, the A2-56RH-C provides the termination reliability that matches the uptime requirements of 24/7 security infrastructure.
