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, automatic 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. 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. All automatic series are available as limit switches (open on temperature rise) or fdan switches (close on temperature rise). Switch action is SPST, SPDT, or DPST with automatice 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 applications 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. • Strap terminals for electric heating • 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 The ranges of temperature settings, tolerances, and nominal differentials shown below are available. Differential is the difference between opening and closing temperature 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 differentials other than those shown, please consult Marketing. Standard Tolerances Mountings and Terminals A variety of terminals and mounting flanges are available to meet installation 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. Highest Temperature Nominal Setting Differential oF oF -10 to 80 81 to 200 10 to 29* 30 to 39 40 to 59 60 to 150 201 to 250 20 to 29 30 to 39 40 to 59 60 to 150 30 to 39 40 to 59 60 to 150 30 to 39 40 to 59 60 to 150 Flanges Available • Small oval bottom flange • Integral surface flange • No flange cup • 3/4” deep cup • Special oval bottom flange Electrical connections to the thermostat must be tight; otherwise, resistance in a loose connection may cause sufficient temperature rise to affect the performance of the thermostat or damage the terminals or the lead wire insulation. 10 to 14* 15 to 29 30 to 59 60 to 150 251 to 300 301 to 350 ** Standard Tolerances Open Close oF ±5 ±6 ±6 ±7 ±5 ±5 ±5 ±6 ±5 ±5 ±6 ±7 ±6 ±7 ±8 ±7 ±8 ±9 ±5 ±6 ±7 ±8 ±5 ±6 ±7 ±8 ±6 ±7 ±8 ±9 ±8 ±10 ±11 ±10 ±12 ±13 • Available in SPST construction only. SPDT thermostats must have 15o minimum differentials. **20413 series – up to 300o 20600 series – up to 350o 20650 / 54 series – up to 300o; minimum differential 30o. 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 depressing 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.
