Working Principle
3MPE Thermal protector is connected to PTC in parallel, then connecting to application in series. PTC doesn’t general high temperature when the application running normally.
When the application works abnormally, which causes the ambient temperature to exceed the prescribed value, the protector will open. Then, the current flows through PTC. Since PTC has a very high resistance, the current assigned to the application will be too low to start it. Meanwhile, the heat generated by PTC will remain the protector open until the power is unplugged.
After the power is unplugged, the ambient temperature will decrease and then, the protector will closed again.
