KI 31/KSD301 series quick action thermostat is a patented technology product of SAFETY Electronics Company.It responds several times faster than a conventional thermostat. KI31/KSD301 bimetal thermostat  is widely used on high power, high heat density and fast heating heater. Such as thick film nano-tubes. Quartz nano-tubes; Nickel-chromium wire wound tube; Resistance heater tube; The ceramic heating tube and instant hot electric heating series. KI31/KSD301 snap disc thermostat is characterized by fast response, low resistance, stable performance, dry burning resistance and large current impact, effectively protect the power attenuation of the thermal heating tube, film burning, tube bursting, deformation, etc., prolong the service life of the heating tube and avoid the occurrence of safety failures.
