Thermik Pressure Resistant Round Thermal Protector S01

The PTC thermistors and thermal protectors produced by the German THERMIK company are stable products successfully developed in 1968. It enjoys a high reputation in the international market and is recognized as an excellent choice for protecting motors, transformers, ballasts, power tools, etc. The temperature switch (thermal protector) produced by THERMIK Company is characterized by its small size, extremely high mechanical stress resistance, high shock resistance, and excellent stability. PTC thermistor is characterized by small size, fast response, 4 layers of protection, and 3 heads connected in series. It can be buried in the three-phase coil of the motor and can protect different temperatures. It can also protect key parts such as motor bearings and lubricants; in this field, THERMIK represents high quality, reliability and durability. Tempertur (TPQE): Thermik's first agent/rare distributor/first-level agent/authorized sales in China.

ST01 series temperature switch
Product advantages:
• Same thermal protection function, low price
• Obtained UL and TUV certification, breaking Germany's 30-year monopoly on temperature switches.
• Good airtightness, which can prevent product failure during the vacuum dipping process.
• Small size, suitable for being buried inside the coil.
• Metal shell, can withstand 50KG coil shaping pressure, has good thermal conductivity, and is sensitive to temperature.
• Pure temperature products, the current does not flow through the bimetal, no current heating effect, accurate temperature control.

technology:
• Integrate global supply chain resources, and the bimetallic sheet uses materials from the world's largest manufacturer, the United States EMS. The shell adopts the stamping and forming technology of German supplier.
• The reed is made of Japanese NGK material, which is processed and produced by Japanese stamping parts suppliers.
• The shell and reed are silver-plated, which greatly reduces the contact resistance.
• The core components of the two pieces adopt fully automated molding equipment and temperature screening tunnel kiln production testing, with good consistency and stable performance.
