FUSE的标示为 T3.15AL250V
不明白中间怎么有个L是什么意思啊?
请知道的大侠告知,谢谢~~

L- 表示低分断能力,请参考如下说明(摘自IEC60065)
14.5.2.2 For fuse-links according to IEC 60127, the following marking shall be located on
each fuse-holder or close to the fuse-link, in the given order:
a symbol denoting the relative prearcing time/current characteristic;
examples are:
F, denoting quick acting;
T, denoting time lag;
the rated current in milliamperes for rated currents below 1 A, and in amperes for rated
currents of 1 A or more;
a symbol denoting the breaking capacity of the assigned fuse-link;
examples are:
L, denoting low breaking capacity;
E, denoting enhanced breaking capacity;
H, denoting high breaking capacity.
Examples of marking: T 315 L or T 315 mA L
F 1,25 H or F 1,25 A H
the voltage rating of the fuse, where a fuse with a lower rated voltage could be fitted in error.

对, 65的标准写的很细,
还有个前提是会影响安全并直接接在供电线路上
