A fall-type fuse is a commonly used short-circuit protection switch for 10kV distribution lines, branch lines, and distribution transformers.

Fusible cutouts are installed on the 10kV distribution line branches, reducing the scope of power outages. With a clear break point, they serve as isolation switches, providing a safe working environment for maintenance sections of lines and equipment.

Mounted on the distribution transformer, it can serve as the main protection for the transformer.

It boasts economic efficiency, ease of operation, and strong adaptability to outdoor environments. Widely used in 10kV power distribution lines and the primary side of distribution transformers for protection and equipment commissioning/cutting operations, it has gained widespread popularity.
