China Thermal Over Temp Protection Switch
A “3MP / 6AP/ 8AM /2AM / 3MP / 17AM+PTC over current & temp bimetallic protector” is a type of electrical safety device that combines a standard ” 3MP ” bimetallic thermal overload protector with a Positive Temperature Coefficient (PTC) termistor, allowing it to both react to excessive current (overcurrent) and high temperatures, automatically cutting power and resetting once the issue is resolved; essentially acting as a resettable fuse with added temperature protection.
