A falling fuse breaker is a commonly used short-circuit protection switch for 10kV distribution line branches and distribution transformers.

Falling fuse breakers are installed on the 10kV distribution line branches, which can reduce the scope of power outages. Thanks to their distinct break point, they provide the function of isolating switches, creating 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 features like economy, ease of operation, and strong adaptability to outdoor environments, and is widely used in 10kV distribution lines and the primary side of distribution transformers for protection purposes and to facilitate equipment installation and disconnection operations, achieving widespread adoption.
