Description
Klixon thermostats have been in
production for over 50 years. The
20413, 20600, and 20650 series
thermostats are especially designed
ed for applications where space,
capacity and ease of assembly are
important production factors. They
are fixed-setting, snap-acting, auto-
matic or manual reset temperature
controls that are ideal for such
applications as: air conditioners,
heating and ventilating equipment,
vending machines, dryers, unit
heaters, tabletop appliances, etc.
All automatic series are available as
limit switches (open on tempera-
ture rise) or fdan switches (close
on temperature rise). Switch action
is SPST, SPDT, or DPST with auto-
matice reset types. Manual reset is
available as a limit switch in SPST
construction only.
The switch mechanism is actuated
by the Klixon snap-action, bimetal
disc which may be enclosed or
exposed. Enclosed disc devices are
particularly recommended for appli-
cations in which dust and lint are
prevalent in the environment.
Exposed disc types are used in
applications where a faster thermal
response to radiant heat is needed.
Contact parts are enclosed for both
disc types for protection against
contamination.
Mountings and Terminals
A variety of terminals and mounting
flanges are available to meet instal-
lation requirements of most
applications.
Flanges can be used for surface or
thru-wall mountings; or, thermostats
can be supplied without flanges for
well or cavity-type mountings.
Flange rotations are specified by
looking down on the terminals and
rotating the flange 30o, 45o, or
90o CW or CCW.
Flanges Available
Small oval bottom flange
Integral surface flange
No flange cup
3/4" deep cup
Special oval bottom flange
Electrical connections to the ther-
mostat must be tight; otherwise,
resistance in a loose connection may
cause sufficient temperature rise to
affect the performance of the ther-
mostat or damage the terminals or
the lead wire insulation.
Terminals Available
Quick connects are available in siver
flash or plain brass.
1/4"Quick connects 0o, 30o, 45o,
90o terminals are male spade type
.250" x .032" thick.
Strap terminals for electric heat-
ing
Brass screw terminals 0o, 45o
When screw terminals are specified,
washer head screws are supplied
unassembled. Assembled washer
head screws are available at extra
cost. Standard screw terminals have
8-32 NC-2 threads.
Temperaturre Settings,
Tolerances and Nominal
Differentials
Standard Tolerances
The ranges of temperature settings,
tolerances, and nominal differen-
tials shown below are available.
Differential is the difference
between opening and closing tem-
perature in oF. For example, a
thermostat which opens at 180oF
and closes at 140oF has a 40o
differential. (Lowest unit prices are
achieved by selecting differentials
in the 30oF to 59oF range). For
temperature settings and differen-
tials other than those shown,
please consult Marketing.
Manual Reset
Construction
There are two basic manual reset
constructions:
1) Manual Override contracts can
be closed at any time after
device has actuated by depress-
ing reset button.
2) Trip-Free contacts will remain
open after device has actuated
until bimetal disc resets, even if
reset button is depressed.
Agency Recognition
Klixon 206 Series Thermostats are
recognized by UL and CSA. Please
consult Marketing for international
approvals.
