Selection of melt rated current
Can be reliable fuse, play a protective role
under the action of short-circuit current and allow overload current ,
There are some equipment starting current is very large, but the start time is very short, so the protection of these devices to meet the needs of the equipment to meet the needs of the operation of the fuse required to start the motor does not fuse
when the load exceeds the allowable value, it is required to protect the melt in a certain period of time fuse
Because a variety of electrical equipment has a certain overload capacity, allowing a long time under certain conditions to run;
