Zoro Select 24C993 4 AWG Compression Lug

This copper compression lug accepts a single 4 AWG stranded copper conductor. It features a one-hole design with a 1/2 inch stud size and a long barrel configuration. The connector is UL Listed and CSA Certified for electrical applications up to 600 V AC. Gray colour coding and die code 29 identify the correct crimping tool.

Verify Wire Size and Stud Compatibility

Confirm the existing conductor is 4 AWG stranded copper before ordering. The lug accommodates a minimum and maximum wire size of 4 AWG only. Ensure the mounting hardware matches the 1/2 inch stud diameter and that the straight tongue orientation fits the terminal block layout. The .69 inch tongue width must suit the available space.

Integrates Into Copper Crimp Connections

The seamless barrel design provides a reliable crimp termination for high-current copper circuits. An inspection hole allows visual verification of full wire insertion after crimping. Rated for a maximum operating temperature of 300 degrees F, it suits demanding industrial environments. This lug requires a compatible crimping tool matched to die code 29 for proper installation.

Questions about this item

Does the lug come with crimp dies or heat-shrink tubing, or must they be purchased separately?

The lug is supplied alone; crimp dies matching die code 29 and any insulation such as heat-shrink must be sourced separately.

How do I choose between barrel lengths or stud sizes for this lug?

This part is a single long-barrel version with a 1/2 in stud hole; no other barrel lengths or stud sizes are offered for model 24C993.

What does the 600 V AC rating mean when the lug is crimped onto 4 AWG copper in a panel?

The 600 V AC rating is the maximum voltage the copper lug can safely carry once properly crimped to 4 AWG stranded copper.
