WebbThe I 2 T rating of a fuse is a related to the energy it lets through to any given load by the resistance of the load. If the load is a linear resistance with a value of R LOAD, then the heating energy in the load will be I 2 T.R LOAD. If on the other hand the load is non-linear, then it is likely to have its own I 2 T withstand rating. Webb16 okt. 2024 · 常用熔断器的工作原理及分类. 先跟大家简单讲下什么是熔断器？. （了解的朋友可以直接跳过这段）熔断器是对电路、用电设备短路和过载进行保护的电器。.
