What is a thermal fuse?
A thermal fuse is also known as a tmperature fuse, 热连接, thermal cut-out (总拥有成本), or one shot. It is a temperature sensing circuit cut-off device (China custom metal, 陶瓷制品, square shell thermal fuse). A limitor thermal fuse can sense the overheating generated by abnormal operation of electrical and electronic products, 从而切断电路，避免火灾.

A limitor thermal cut-out fuse functions as a safety device that automatically interrupts an electrical circuit when the temperature reaches a predetermined threshold, essentially acting as a “heat-activated circuit breaker” to prevent overheating and potential fire hazards in appliances or equipment by cutting off power when excessive heat is detected; it’s primarily used in devices like hairdryers, 烘干机, 咖啡机, and electric motors where overheating could occur due to malfunctioning components.

Key points about thermal fuses:
How it works:
When the temperature around the thermal fuse exceeds its rated temperature, a special fusible material inside melts or breaks, causing the circuit to open and stopping the flow of electricity.

Non-resettable:
Unlike regular fuses, a thermal fuse cannot be reset once it has tripped and needs to be replaced if overheating occurs.

Its structure and working principle:
It consists of a sliding contact , 一个春天, and a electrically nonconductive thermalpellet. Before the thermal fuse is activated, 电流从左引线流向动触头 (滑动接触), 并通过金属壳流向右侧引线. 当外界温度达到预定温度时, the fusible element melts and the compression spring becomes loose. 那是, 弹簧膨胀, and the sliding contact separates from the left lead. 电路已打开, and the current between the sliding contact and the left lead is cut off.

Temperature-sensitive only:
Unlike a standard circuit breaker, a thermal fuse only responds to temperature changes, not current surges.
应用领域:
家用电器: Hairdryers, 烤面包机, electric blankets, Transformers, Electric motors, Electric fans, Hair dryers, Electric irons, Rice cookers, Copiers, Electric stoves, Chargers, power taps, Water dispensers, Coffee makers etc.
Motor applications: Electric motors in appliances and machinery
Industrial equipment: Transformers, heating elements, 电动工具.
