Temperature switch classification and selection

The temperature switch has the characteristics of small size, outer casing insulation, sensitive action and long service life. It is widely used in various motors, induction cookers, vacuum cleaners, coils, transformers, electric heaters, ballasts, electric heating appliances, fluorescent lamp ballasts, Double protection of overheating and overcurrent of automotive motors, integrated circuits and general electrical equipment.

Temperature control switch classification

By model: BW KW BR KSD9700 ST-22 AMT RS9700 KSD01F JUC31F JUC1M

According to the brand can be divided into: Winning temperature switch Emerson temperature switch NEC temperature switch

Divided by temperature: 0 degrees 5 degrees 10 degrees 15 degrees 20 degrees 25 degrees 30 degrees 35 degrees 40 degrees 45 degrees 50 degrees 55 degrees 60 degrees 65 degrees 70 degrees 75 degrees 80 degrees 85 degrees 90 degrees 95 degrees 100 degrees 105 degrees 110 degrees 115 degrees 120 degrees 125 degrees 130 degrees 135 degrees 140 degrees 145 degrees 150 degrees 155 degrees 160 degrees 165 degrees 170 degrees 175 degrees 180 degrees 185 degrees 190 degrees 195 degrees 200 degrees 205 degrees 210 degrees 215 degrees 220 degrees 225 degrees 230 degrees 235 degrees 240 degrees 245 degrees 250 degrees 255 degrees 260 degrees 265 degrees 270 degrees 285 degrees 275 degrees 280 degrees 290 degrees 295 degrees 300 degrees

According to the nature of the action: normally open type normally closed type

KSD301 thermostat precautions

(1) Grounding method: Connect to the grounding metal parts of the equipment through the metal cover of the thermostat.

(2) When using contact temperature sensing, the metal cover should be close to the mounting surface of the controlled appliance. To ensure the temperature sensing effect, the temperature sensitive surface should be coated with thermal grease or other similar heat transfer medium.

(3) Do not crush, loosen or deform the top of the cover during installation to avoid affecting performance.

(4) Do not allow liquid to penetrate into the interior of the temperature controller. Do not allow cracks in the casing. Do not change the shape of the external terminals.

(5) The product should be used in a circuit with a current of no more than 5A. The copper core should be selected from 0. 5-1mm2 wire connection; if the circuit is not more than 10A, the copper core should be 0.75-1.5mm2 wire connection. .

(6) The product should be stored in a warehouse with a relative humidity of less than 90% and an ambient temperature of 40 ° C below, which is ventilated, clean, dry and free of corrosive gases.

(7) The terminal cannot be bent during use, otherwise the reliability of the electrical connection will be affected.
