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. File No. E9977 U.S. Guide No. XAPX2 Canada Guide NO.
