Panduit A1-38R-C 1AWG/3/8" Compression Lug - 100pk

Panduit A1-38R-C 1 AWG Compression Lug for 3/8" Stud

The Panduit A1-38R-C Pan-Lug compression lug delivers code-compliant battery cable termination for 1 AWG conductors onto 3/8-inch stud terminals. Built for UPS installations, backup battery systems, and DC power distribution in datacenters and critical infrastructure, this tin-plated copper lug provides low-resistance connections that meet UL 486A-486B power application standards and US Military wire pull-out specifications. The 100-piece pack supports large-scale installations where bulk purchasing reduces per-termination cost and minimizes job-site reorders.

Key Features

• 1 AWG wire size with 3/8" stud diameter for common UPS and battery cabinet terminals
• Tin-plated copper construction prevents oxidation and maintains conductivity in harsh environments
• Flared barrel entry simplifies conductor insertion and reduces installer fatigue on high-volume jobs
• Embossed wire size marking on barrel eliminates guesswork during mixed-gauge installations
• cULus Listed to UL 486A-486B for power applications in US and Canada
• Meets US Military wire pull-out specifications for high-stress applications
• 100-pack quantity supports multi-cabinet UPS installations and datacenter power distribution projects

This compression lug uses a barrel design that accepts 1 AWG stranded copper conductors and compresses onto the wire using a hex die compression tool. The tin-plated finish resists corrosion from humidity and airborne contaminants common in electrical rooms and outdoor battery enclosures, maintaining long-term contact resistance below industry thresholds. The 3/8-inch stud hole diameter matches standard terminal posts on sealed lead-acid batteries, lithium-ion UPS systems, and DC distribution busbars. Embossed wire size markings remain legible after installation, helping inspectors and maintenance techs verify proper gauge matching without destructive testing.

In multi-battery UPS installations, the A1-38R-C handles the repetitive terminations across dozens of inter-battery cables and bus connections without quality degradation. The flared barrel entry reduces the physical effort needed to insert stripped conductors, cutting installation time per termination by 15-20% compared to straight-barrel designs. The high pull-out strength rating ensures connections survive seismic events, thermal cycling, and vibration in mission-critical facilities. When paired with properly sized compression tooling, these lugs create gas-tight connections that eliminate the oxide layer formation and hot spots associated with mechanical set-screw or bolt-on lugs.

Compliance with UL 486A-486B and Canadian electrical standards makes the A1-38R-C suitable for inspected installations in commercial buildings, healthcare facilities, telecom central offices, and industrial plants. The cULus listing covers both power distribution and grounding applications, reducing the need to stock separate lug types for different circuit classes. Bulk packaging in 100-piece quantities aligns with the typical cable count in large UPS installations—a 40-cabinet datacenter UPS build might require 80-120 lugs for inter-battery strings alone, making the factory pack size a practical match for real-world project scope.
