Question:

Switch current setting value is what that means,

Switch current setting value is what that means, why the setting value should be less than the conduction capacity of the wire to be able to play a protective role, experts please give pointers, thank you

Answer:

If the current is greater than the set value, the switch should operate. If the action value is greater than the conductor carrying capacity, the wire may not be protected. The main function of the switch is to protect the transformer and the wire.

Only in this way can the line overcurrent or short circuit when the first fuse fuse fuse! Otherwise the wire burned off the switch did not move.

Such as 20A switch set current, its setting current can be adjusted from 0 to 20A arbitrary, when the rated current of the electrical equipment is 10A, its setting current to take less than or equal to 10A, otherwise it can not reach the protective effect.
