Siemens TYPE VBII Series User Manual

Description & Application
Double throw safety switches are
intended to transfer loads from one
power source to another. All two- and
three pole double throw switches are
suitable for use as service equipment.
All are UL listed. Switches are rated for
use on systems up to 10,000A when
protected with Class H fuses or
100,000A when protected with Class R
or Class T fuses¡. They can also be used
to connect a single source of power to
either of two loads. In this application it
is necessary to field modify fusible
switches so that the fuses are on the
load side of the switching mechanism.
A cover interlock is provided on all
ampere ratings. The operating handle
may be padlocked in the OFF position.
