Techspan® SLU400 | Copper Mechanical Lug - One Hole Offset Tongue 500 kcmil-1/0 AWG

The SLU400 copper mechanical lug is designed for terminating and connecting stranded copper conductors in power distribution and electrical equipment. It accepts copper cable sizes from 500 kcmil to 1/0 AWG stranded and is rated for applications up to 400 amps.

Made from electrolytic copper, this lug provides strong electrical conductivity and dependable mechanical strength. The one-hole, single-collar design allows for secure mounting to equipment pads, terminals, and bus bars.

The offset tongue helps improve cable positioning during installation. This makes it easier to connect conductors in panels, switchgear, and other electrical assemblies where alignment can be a challenge.

Key Features:

• Accepts 500 kcmil to 1/0 AWG stranded copper conductors
• One-hole, single-collar mechanical lug design
• Electrolytic copper construction for high conductivity
• 400 A NEC ampere rating
• Offset tongue for easier cable-to-equipment connections
• Concave pressure bar for improved conductor contact
• V-bottom collar design for a secure hold on the conductor
• Plated steel set screws help resist corrosion
• UL Listed
• CSA Certified
• RoHS Compliant

Typical Applications

The SLU400 is commonly used in switchgear, panelboards, control panels, distribution equipment, and grounding systems. It is suitable for commercial, industrial, and utility applications where large copper conductors require a reliable mechanical termination.

Its combination of high-conductivity copper construction, corrosion-resistant hardware, and secure clamping design helps maintain a solid electrical connection over the life of the installation.
