When Selecting The Specifications Of A Drop-out Fuse, The Maximum Load Should Be Taken Into Account.

When designing power lines, the appropriate drop out fuse element specification can be selected based on the system's maximum load. First, compare the maximum continuous operating current of the line or equipment with the rated current of drop out fuse in transformer. Generally, the rated current of drop out fuse price should be greater than or equal to the maximum load current.

For power supply transformers or distribution lines, the maximum load conditions that may occur during operation should be calculated. For example, startup or short-term high-power conditions may cause a sudden increase in current. In this case, drop out fuse set should simultaneously meet the rated breaking current and the system's maximum expected short-circuit current conditions.
