How To Select A Drop-out Fuse Based On The Rated Current Of The Circuit.

When designing a power system, the drop fuse cutout should be selected based on the rated current of the circuit. Based on the actual operating current value of the circuit, when selecting drop out expulsion fuse, its rated current should be greater than or equal to the rated current of the line. This ensures that the drop out fuse 22kv circuit breaker will not trip due to slight fluctuations when the load is running normally.

When selecting a model, the rating of the drop out fuse 33kv is usually determined based on the circuit type and load characteristics. For example, for transformer-powered circuits, the rated current of the drop out fuse cut out timer is usually selected to be 1.5 to 3 times the rated current of the transformer to ensure that it will not malfunction during startup or load fluctuations.
