3M™ Scotchlok™
Copper/ Aluminum
Compression
Lugs, 40000 Series
Data Sheet
Description
October 2015
3M Scotchlok Copper/Aluminum Compression Lugs 40000 Series are made of high
conductivity aluminum and are designed to cover a wide range of conductor sizes
from 6 AWG through 1000 kcmil (MCM). The lugs consist of a series of one-hole
lugs ranging from 6 AWG through 1000 kcmil (MCM) and two-hole lugs, for
increased secureness requirements, ranging from 1/0 AWG through 1000 kcmil
(MCM). They are designed to terminate either aluminum or copper conductors.
Each lug is electro-tin plated to resist electrolytic corrosion. They are installed using
standard industry tooling. Chamfered ends ensure simplicity and ease of conductor
insertion.
UL Listed, UL Standard 486A-486B, File No. E23438

Typical Properties
Not for specifications. Values are typical, not to be considered minimum or maximum.
Properties measured at room temperature 73°F (23°C) unless otherwise stated.
3M Scotchlok Copper/Aluminum Compression Lugs, 40000 Series, when crimped with
approved die sets, can be used on cables with an operating temperature of 194
°
F
(90
°
C) and an emergency overload rating of 266
°
F (130
°
C). The lugs pass the
requirements of UL486B (Underwriters Laboratories standard for safety). The current
rating of these lugs meets or exceeds the current rating of the conductor size for which
it is intended.
Tool/Installation
Information
Lugs shall be crimped with one of the approved die sets according to the
engineering information supplied with the lugs. (Also see Crimping Tool-Die Sets
table below). If different crimping tools and die sets are used, consult the tool
and die manufacturer.
