KSD302 140C 16A 250V normal close NC Ceramics thermostat KSD301 16A250V 140degree CQC thermal control | Обустройство дома

Product Name: Snap thermostat switch Brand: China Model : KSD301/KSD302 Body material : Bakelite , ceramics Switch Type : normally closed / normally open Operating voltage : 110V, 250V, 400V (V) Overload current : 5A, 10A, 15A, 20A, 40A, 60A Operating temperature : 0 degrees to 300 degrees (Degree) Life: 50000 ( times )   Product characteristics, uses and working principle     The company specializes in the production of various series of bi-metallic thermal protection, temperature control, temperature switches and RH low melting alloy type thermal fuse, using a variety of products assembled from imported materials , sophisticated production equipment, detection means complete, the the company has strong technical strength and rich experience in the production of quality assurance as a powerful backing .   Features: bimetal contact sensing, fast -acting , sensitive , reliable, safe , fixed operating temperature , long life, no arcing .   Uses : mainly used motor motor dispenser, electric open water bottles , sterilizer , coffee husks , electric iron , dryers , air conditioners , water heaters , electrical cooker, heater, vacuum cleaner motor Qingdu cupboards and other appliances .   Working principle: the use of bimetal disc as a temperature sensing member , the thermostat works as follows: When the temperature rises, the corresponding disc will have deformed sheet , and when the temperature reaches the disc deformed sheet value, disc film jumps rely on other mechanical transmission device , the contacts to quickly connect or disconnect the current action .   Technical Specifications: 1 ) Rated voltage : 250V/5A, 125V/15A, 250V/10A, 400V/20A, 400V/60A 2 ) Operating temperature accuracy : ± 3, ± 5 3 ) Operating temperature range : 0 Degree  -300 Degree ( other specifications can be designed according to need ) . 4 ) Contact life : more than 50,000 times ( number of operations ) 5 ) Contact resistance : Less than 100m ( according to the design needs to be given separately ) 6 ) Electric Strength : AC50Hz, 2000V/min no breakdown and arcing . 7 ) Insulation resistance : greater than 100 m (DC500V ohm meter ) 8 ) Contact Status: normally closed at room temperature (normally open ) , the temperature reaches a preset point contacts open ( closed ) 9 ) Heat Level: +35 Degree operating temperature   Note: 1 When installing non- metallic enclosure collapsed or deformed , so as not to change the value of the operating temperature and affect other functions ; 2 manual reset thermostat reset operation , the thermostat must be reduced to below the nominal operating temperature for the next 15 Degree, the thrust should be less than 30N, so as not to damage the reset mechanism
