Motor thermal protection
Motor thermal protection PTC thermistor
Polymer PTC temperature sensor. A surface mount polymer PTC (positive temperature coefficient) temperature sensor using a conductive polymer polymer composite material as a main material. Different from the traditional ceramic PTC temperature sensor, it adopts an easy-to-install surface-mount form for easy installation;
thermal fuse and circuit breaker cutoff temperature
They are the same in that they can achieve short circuit protection. The principle of a thermal fuse is to use a current flowing through a conductor to cause the conductor to heat up. When the melting point of the conductor is reached, the conductor is melted so that the circuit-protected electrical appliances and lines are not burned.
