PTC will not work. When the application works abnormally, which causes the ambient temperature exceeds 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 close again. Casing seal Certification: UL&CUL:E258612
