Data Sheet
October 2015
Description
3M Scotchlok Copper/Aluminum Compression Connectors, 20000 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). They are designed to connect either
aluminum and/or copper conductors. Each connector is electro-tin plated to resist
electrolytic corrosion. They are installed using standard industry tooling.
Chamfered ends, and an integral solid center barrier,* ensure simplicity and ease of
conductor insertion.
*NOTE:
20001 and 20002 connectors have bore protrusions rather than a solid
center barrier.

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 Connectors 20000 Series, when
crimped with approved die sets, can be used on cables with an operating temperature
of 194
o
F (90
o
C) and an emergency overload rating of 266
o
F (130
o
C). The connectors
pass the requirements of UL486B (Underwriters Laboratories standard for safety).
The current rating of these connectors meets or exceeds the current rating of the
conductor size for which it is intended.
Tool/Installation
Information
Connectors shall be crimped with one of the approved die sets according to the
engineering information supplied with the connectors. (Also see Crimping Tool-Die
Sets table below). If different crimping tools and die sets are used, consult the tool
and die manufacturer.
