YS11 small thermal protector series  

YS11 series temperature switch is a miniature thermal protector, suitable for small spaces, fast trip action, reliable performance, minimum trip temperature of 45 ℃ can be selected, and accurate reset temperature

Product Details
Working principle of YS-11 thermal protector
The YS11 temperature switch is a temperature sensing protector produced by Texas Instruments KLIXON® proprietary technology, which is very sensitive to temperature changes. When an accident occurs, the rising temperature causes the KLIXON ® bimetal to open quickly. When the device cools down to a safe temperature, the contacts close automatically,
Competitive advantages of YS11 thermal protector industry
Miniaturized design, the minimum trip temperature of 45 ℃ can be selected, and there is an accurate reset temperature.
  • Each trip temperature is strictly calibrated and checked. The bimetal (KLIXON ® patented brand) has 100% rapid trip;
  • The design of the pure temperature bimetallic induction action increases the on-current;
  • When used as a protector for batteries and battery chargers, it has overheating and short circuit protection;
  • Hard shell support protects internal components from paint leakage and damage from external mechanical forces
  • Large current capacity and long service life.
  • Accurate action temperature without action peristalsis;
  • Various specifications and lengths of wire can be riveted according to customer needs
  • Passed national safety certifications: UL, CSA, VDE, ENEC (European Union), KEMA, CQC ... certificates, and meet EU ROHS environmental protection requirements.
