Question:

Fuse according to the breaking current range can be divided into several

Fuse according to the breaking current range can be divided into several

Answer:

This fuse is often used in series with the contactor, the overload current is less than the rated current of 4 to 7 times the range, by the contactor to achieve breaking protection. Mainly used to protect the motor.
The breaking current range of the back-up fuse refers to a range from 4 to 7 times the rated current from the rated current to the maximum breaking current
This fuse is mainly used to protect power transformers and general electrical equipment.
General Purpose The breaking current range of the fuse refers to a range from the load current greater than the rated current of 1.6 to 2 times to the maximum breaking current.
