Burndy YAD4CM5E10 Compression Terminal 4 AWG #10 Stud Long

SKU CH-0B3D-TA3X3

Uninsulated copper compression terminal crimps 4 AWG wire to a #10 stud with a long brazed barrel rated 600 V

  • TypeElectrical Connectors
  • Rated for 600 V circuits with UL 467 listing
  • Tin-plated copper barrel resists corrosion in harsh environments
  • Brazed seam barrel prevents splitting under high crimp force
  • Long 0.43 in barrel gives more crimp contact area
  • Fits 4 AWG wire and #10 stud for secure connections

Terminal Purpose

The Burndy YAD4CM5E10 is an uninsulated copper compression terminal built for 4 AWG conductors that terminate on a #10 stud. It serves installers who need a reliable crimp connection in panels, equipment or automotive wiring where a bare barrel is specified.

Critical Specification

The barrel accepts exactly 4 AWG wire and the tongue is drilled for a #10 stud, so the terminal only fits that conductor size and bolt pattern. Tin-plated copper and a brazed barrel meet UL 467 and withstand 600 V at up to 302 °F, confirming the electrical and thermal envelope the connection must satisfy.

Installation Notes

A proper crimp tool sized for 4 AWG and a long barrel is required; using the wrong die leaves a loose joint that can overheat. The bare barrel offers no insulation, so clearance to adjacent live parts must be verified, and the 0.47 in tongue width should match the busbar or lug spacing before the crimp is made.

Questions about this item

What does the 600 V rating mean when the terminal is crimped on 4 AWG wire?

The 600 V rating is the maximum voltage the copper barrel and tin-plated contact can carry once the 4 AWG conductor is properly crimped in the .43 in long barrel.

How does the UL 467 standard apply to this #10 stud ring terminal?

UL 467 covers grounding and bonding connectors; this terminal meets that standard for use on a #10 stud in grounding applications up to 600 V.

What clearance does the .47 in tongue width and long .43 in barrel need on a #10 stud?

The .47 in tongue fits a #10 stud with standard clearance, while the .43 in long brazed barrel requires a crimp tool sized for 4 AWG long barrels.
