A fall-type fuse breaker 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 distinct break point, they offer the functionality of isolating switches, creating a safe working environment for maintenance sections of lines and equipment.

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

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