Burndy Aluminum Compression Lug, 1-Hole, Short Barrel, Tin-Plated

The Burndy Aluminum Compression Lug is a Type YA-A HYLUG™ terminal engineered for permanent, trouble-free electrical terminations on both aluminum and copper conductors from #12 solid through 2000 KCMIL. Built from high-conductivity wrought aluminum and finished with a durable electro-tin plating, this 1-hole, short-barrel lug is rated for heavy-duty applications up to 35 kV and is UL Listed for 90°C, 600V-35kV service. Each terminal is factory-prefilled with PENETROX oxide-inhibiting compound and capped with color-coded end caps for a reliable, code-compliant connection.

Key Features

  • Durable Aluminum Construction: Manufactured from high-conductivity, wrought aluminum with heavy-duty wall thickness for maximum conductivity, low resistance, and excellent crimp-forming ductility.
  • Electro-Tin Plated Finish: Provides durable, long-lasting corrosion resistance for reliable service life.
  • 1-Hole Configuration, Short Barrel: Designed without an inspection window, with an internally bevelled barrel that provides easy cable insertion.
  • Dual-Rated Termination: Designed for use on both aluminum and copper conductors from #12 solid through 2000 KCMIL.
  • Voltage Rating: UL Listed 90°C, 600V-35kV, suited for heavy-duty applications to 35 kV.
  • Prefilled with PENETROX: Oxide-inhibiting compound with homogeneously suspended metallic particles penetrates wire oxides, establishes electrical continuity, and forms an airtight connection.
  • Color-Coded End Caps: Inserted in the barrel end to prevent foreign material contamination and identify the proper color-coded die for a reliable connection.
  • UL486B Compliant: Meets UL486B 90°C requirements for a quality, dual electrical connection.

Burndy YA25A3 – Frequently Asked Questions

1) Can Burndy YA-A HYLUG compression lugs be used on aluminum and copper conductors?
Yes, the Type YA-A HYLUG is a dual-rated terminal for both aluminum and copper conductors. The body is wrought aluminum with electro-tin plating, and each barrel comes prefilled with PENETROX oxide-inhibiting compound so an aluminum conductor's oxide layer is broken down at crimp. That prefill is why you don't need to brush and paste the conductor separately before crimping.
2) What wire sizes do these Burndy HYLUG aluminum lugs come in?
Four conductor sizes are offered: 1/0 AWG (YA25A3), 2/0 AWG (YA26A1), 3/0 AWG (YA27A3) and 4/0 AWG (YA28A3). Each lug is sized to one conductor, so order by the exact AWG you are terminating rather than trying to double up a smaller conductor in a larger barrel.
3) Is the Burndy HYLUG YA-A lug rated for medium voltage cable terminations?
It is. The YA-A HYLUG is UL Listed at 90 degrees C for 600V through 35kV, so it covers both 600V feeder work and medium-voltage terminations up to 35 kV in switchgear and pad-mount applications. The 90 degree C rating means it can be used with 90C insulated conductor without derating the connector itself.
4) How do I know which crimp die to use with a Burndy compression lug?
Each barrel is capped with a color-coded end cap, and that color identifies the matching color-coded die for the crimp. The cap also keeps dirt and moisture out of the prefilled PENETROX before you make the termination, so leave it in place until the conductor goes in.
5) Will a 1-hole lug work on a two-hole NEMA bolt pattern busbar?
No. This HYLUG is a 1-hole terminal with a straight, standard tongue, so it lands on a single bolt. A NEMA two-hole pad requires a two-hole lug with the correct center-to-center spacing. Use the 1-hole YA-A where the pad, breaker lug pad, or ground bar takes a single bolt.
6) Does this Burndy lug have an inspection window for checking conductor insertion?
No. The short-barrel YA-A is built without an inspection window. The barrel is internally chamfered so the conductor feeds in easily, but you confirm full insertion by measuring your strip length against the barrel depth rather than sighting a window. If your spec or inspector requires a window, you need a window-style HYLUG instead.
7) Does the Burndy YA-A HYLUG carry CSA or cULus approval for a Canadian job?
The YA-A is UL Listed only. It is not CSA approved, not cULus, not ETL, and it is not a UL Recognized component. For work that must be CSA certified, specify a lug carrying that mark.
8) What standards does the Burndy HYLUG aluminum compression lug meet?
It meets UL468A-468B and satisfies UL486B 90 degrees C requirements for dual-rated AL/CU connections. That combination is what inspectors typically look for on an aluminum feeder termination in commercial and industrial panelboard and switchgear work.
9) Will the tin plating on these lugs hold up in a damp or outdoor enclosure?
The electro-tin plating over wrought aluminum is there for corrosion resistance, and it also gives you a tin-to-tin or tin-to-plated-bus interface rather than bare aluminum against copper, which is what causes galvanic trouble at a termination. Combined with the factory PENETROX in the barrel forming an airtight seal on the conductor side, it holds up in typical industrial enclosure environments.
10) What is the barrel length on the Burndy short barrel HYLUG?
The catalog N dimension on the YA-A short barrel is 0.63 inch. Short barrel matters when you are terminating in a tight breaker throat or a crowded switchgear compartment where a long-barrel lug will not clear the cable bend.
