The S01 thermostat is a thermal protector. It features a compact design with silver-plated copper shell and utilizes a bimetallic component. S01 Button type is snap action and bimetallic thermostat. Bimetal trips off or on quickly to open or close the circuit when temperature reaches the prescribed value.

Advantages of S01 Thermal Protector
1. Global Supply Chain Integration: The S01 thermostat leverages global supply chain resources. The bimetallic component is made with materials from EMS, the world's largest bimetallic manufacturer based in the United States. The shell of the thermostat utilizes stamping and forming technology from a German supplier.
2. Bimetallic Component and Spring Material: The bimetallic component, responsible for temperature sensing, utilizes materials sourced from NGK in Japan.

The processing and production of the bimetallic component are carried out by a Japanese stamping parts supplier.
3. Silver Plating: Both the shell and the spring of the thermostat undergo silver plating. This silver plating process significantly reduces contact resistance.
4. Automated Production and Testing: The bimetallic component, being a core part of the thermostat, is produced and tested using fully automated molding equipment and temperature screening tunnel kilns. This automated production process ensures good consistency and stable performance of the thermostat.
