Compression
Connectors 20000 Series
Data Sheet June 2012
Description
3M™ Scotchlok™ Cop per/Aluminum Compression Conne ctors, 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 copp er 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 insertio n.
*NOTE: 20001 and 20002 connectors have bore protrusions rather than a solid
center barrier.

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 Conne ctors 20000 Series, when
crimped with approved die sets, can be used on cables with an operating temperature
of 221oF (105oC) and an emerg en cy overloa d rating of 284oF (140oC). 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 intende d.
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.
