Burndy KPA34 SCRULUG Pressure Bar Copper Lug

Burndy KPA34 SCRULUG Pressure Bar Copper Lug, 1-Hole, Tin-Plated

The Burndy KPA34 is a SCRULUG™ mechanical copper lug with a pressure bar design built for secure, code-compliant terminations. This 1-hole lug features a 1/2" stud and accepts 4/0 AWG stranded through 500 kcmil copper conductors, making it a dependable choice for heavy-gauge power and grounding connections in commercial and industrial electrical systems. Solid copper construction with a tin-plated finish provides reliable conductivity and long-term corrosion resistance in demanding electrical environments, while the pressure bar clamping method allows for a repeatable, high-quality mechanical connection without the need for specialized crimping tools.

Key Features

• Stud Size: 1/2" stud accommodates standard mounting hardware for a secure, vibration-resistant connection to busbars and equipment pads.
• Durable Construction: Solid copper body delivers excellent electrical conductivity, mechanical strength, and long service life in continuous-duty applications.
• Pressure Bar Design: Mechanical SCRULUG™ pressure bar provides even, high-pressure clamping across the full conductor surface without nicking or damaging individual strands.
• 1-Hole Configuration: Single-hole mounting pad simplifies installation on busbars, panelboards, switchgear, and other equipment terminals.
• Wide Conductor Range: Accepts 4/0 AWG stranded through 500 kcmil copper conductors, giving installers flexibility to standardize on a single lug across multiple wire sizes.
• Corrosion-Resistant Finish: Tin-plated copper resists oxidation and maintains a stable, low-resistance connection point over the life of the installation.
• Field-Installable: Mechanical set design allows installation with standard hand tools, without requiring a hydraulic crimping die.
