What is a thermal fuse?
A thermal fuse is also known as a tmperature fuse, 열 링크, thermal cut-out (TCO), or one shot. It is a temperature sensing circuit cut-off device (China custom metal, 세라믹, square shell thermal fuse). A limitor thermal fuse can sense the overheating generated by abnormal operation of electrical and electronic products, 화재를 피하기 위해 회로를 차단합니다..

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, 건조기, 커피 메이커, and electric motors where overheating could occur due to malfunctioning components.

Key points about thermal fuses:
작동 방식:
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 , 봄, and a electrically nonconductive thermalpellet. Before the thermal fuse is activated, 왼쪽으로부터의 흐름은 움직일 수있는 접촉으로 이어집니다. (슬라이딩 접촉), 금속 쉘을 통해 오른쪽 리드로 흐릅니다.. 외부 온도가 미리 정해진 온도에 도달 할 때, the fusible element melts and the compression spring becomes loose. 그게, 스프링이 팽창합니다, and the sliding contact separates from the left lead. 회로가 열립니다, 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.
