Product description

KI-67 series common and enhanced thermal protector are widely used electric motors of industrial, household appliance and other electric equipment. The KI-67 series can effectively and reliably guard against the damage caused by overflow and overheat. The shell of enhanced type is applicable to the internally installed plastic sealed motors and is capable of tolerating the 3.5Mpa technical pressure for plastic molding . The performance complies with the standards of IEC34-11, GB13232 and GB/T 13002 etc .

KI-66 series thermal protector is composed by heat conductive metal shell, bimetal component
Welded silver alloy contact , current conductive frame, insulated fixing seat, static contact pad heat resistant wires ate. When the current goes through the bimetal component with impedance, if the current increases or the environment temperature rises and the temperature reaches the preset value, the bimetal component will work and release the contact to shut off the circuit; and by contrast, if the device cools down to the safe temperature, the contact point will reset automatically.
