Sprecher + Schuhs larger L7 Mo-
tor Disconnect Switches extend your
range of applications up to 315A.
These sturdy switches are compact,
reliable and the ideal choice for the
rigorous demands of motor disconnect
switching.
Flexible switch choices
Two frame sizes provide a range of
disconnect switches rated from 125
to 315 amps. Base and panel mount
switches are available in both three and
four poles. In addition, all switches are
available with either box lugs or bolt-
on terminals. Box lugs are typically
used in most applications, however,
bolt-on terminals may be preferred in
this size switch, particularly in appli-
cations where vibration could loosen
connections.
Convenient accessories
Base mount L7 switches come stan-
dard with a 195mm
(
7-3/4)
metal
shaft that can easily be cut to the
correct length. A longer shaft is
also available. Accessories including
auxiliary contact blocks, ground and
neutral terminals snap-on without the
use of tools. Terminal covers are also
available.
Safe and reliable
High short circuit withstand capabil-
ity ensures a minimum probability of
contact welding. Switches with box
