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.
