TO-220 PCB-Bimetal Disc Small Thermal Protection Thermostat
JUC 31F / ST01 B U8 Series TO-220 PCB-Bimetal Disc Thermostat: A snap action SPST bimetallic thermostat that meets RoHs standards.
JUC 31F / ST01 B U8, 6700 Series TO-220 Subminiature Thermostat: A subminiature bimetal disc thermostat with a contact resistance of 50 milliohms max. It has a switch capability of up to 2 amp for 48 VDC or 120 VAC for 30,000 cycles.
A TO-220 PCB-Thermal protection Thermostat is a method that detects high temperatures and disconnects power to electronic circuits to prevent damage or fires. A TO-220 PCB- Thermal protectors Thermostat are often used in motors to prevent overheating and fires by turning off the electricity when the motor’s heat rises too high. Thermal protectors are usually placed inside the motor.
A TO-220 PCB-bimetal disc thermostat is a thermally actuated switch that uses a bimetallic disc to sense temperature and open or close an electrical circuit. When the disc is exposed to a predetermined temperature, it snaps and either breaks or completes the circuit. Here are some examples of TO-220 PCB-bimetal disc thermostats:

PCB-Bimetal Thermostat Connection structure
The static contact and ceramic cover are riveted; The moving contact is welded to the reed, which is in the shape of a cross, and its four legs are connected to the bottom of the shell; The inner hole of the bimetallic strip passes through the moving contact and is placed on the reed. The current passes through the static contact to the moving contact, and then connects to the shell through the reed to form a loop.
ST01 B U8 PCB-Bimetal Thermostat Working principle
When the circuit is in normal state, the moving contact is in close contact with the static contact under the pre-pressure of the reed. When the temperature reaches the operating temperature, the bimetallic strip is deformed by heat and quickly flips, pressing the reed to move downward, causing the contacts to separate and cut off the circuit. After the circuit is cut off, the temperature begins to drop. When the temperature drops to the reset temperature, the bimetallic strip returns to its initial state, and the reed also rebounds to its initial state. The moving contact and the stationary contact re-contact, and the circuit returns to the normal conduction state.
