Thermal Protection Function

This thermal protection switch is typically installed on A/C compressor housings to prevent compressor damage from overheating caused by internal friction. The switch monitors compressor case temperature and interrupts the electrical circuit when a predetermined temperature threshold is reached.

Protection Mechanism

The thermal protection switch guards against overload conditions. This is achieved through a bra shaft placed inside a brass tube in solder pot relays, where motor current passes through a small heater winding.
