l-56 Electr ical Interlock
Description
L-56 electrical interlocks are designed to be
used as auxiliary control contacts for West­
inghouse A/200 contactors. One interlock
fits all sizes from 00-4. Because the L-56
mounts within the outside dimension of the
contactor, four interlocks per contactor can
be added without any increase in panel area.
The L-56 is held in position by two attached
spring clips so no mounting hardware or
tools are required. For easy wiring, inter­
locks are designed to mount in either of two
90' positions, whichever is more convenient
to the user. See illustration.

Design
Description
The mechanical interlock for A/200 devices
is a self contained unit either factory assembled
on complete reversing or multispeed
devices or is available in kit form for
field mounting, The mechanical interlock is
a lever type mechanism which prevents any
closing motion of one member of a reversing
or multi-speed contactor or motor controller,
until the opposing member is essentially
completely open.

Time Delay Interlock
The Westi nghouse solid state time delay
interlock provides accurate, re liable timing
in a minimum of panel space. Field mountable
in the interlock cavity of A/200 starters and
contactors, it has one NO contact. Designed
to switch a 120 volt Ac coil. it may be wired
in series with the starter or contactor coil. It
is also available with a mounting plate for
panel use.
