Introduction
As a non-resettable one-time action thermal protection device, the thermal fuse is an irreplaceable and important over-temperature protection component:
Widely used in household appliances and industrial equipment; when the electrical equipment fails or is abnormal, the heat exceeds the set allowable temperature
, rely on thermal fuses to actively cut off the circuit for protection, so as to avoid the danger of damaging the safety of electrical equipment: Therefore, the production of thermal fuses
Product quality and performance are directly related to the safety of the whole machine and even the safety of people and the environment:
GB/T 9816 aims to standardize the technical requirements for thermal links, and is intended to be composed of three parts:
