3M™ Scotchlok™
Copper/ Aluminum
Compression
Lugs, 40000 Series
Data Sheet January 2014
Description
3M™ Scotchlok™ Cop per/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 throug h 1000 kcmil (MCM) and two-hole lugs, for
maximum secureness requirements, ranging from 1/0 AWG through 1000 kcmil
(MCM). They are design ed to terminate either aluminum or copper conductors.
Each lug is electro-tin plated to resist electrolytic corrosion. They are installed using
standard industry tooling. Chamfere d ends ensure simplicity and ease of conductor
insertion.

Typical P roperties
Not for specifications. Values are typical, not to be considered minimum or maxi mum.
Properties measured at room temperature 73°F (23° C) unless otherwise stated.
3M™ Scotchlok™ Cop per/Aluminum Compression Lu gs, 40000 Series, when crimped
with approved die sets, can be used on cables with an operating temperature of 221oF
(105oC) and an emergency overload rating of 284oF (140oC). The lugs pass the
requirements of UL48 6B (Underwriters Laboratories standard for safety). The current
rating of these lugs meets or exceeds the current rating of the conductor size for whi ch
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)
