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

The fall-type circuit breaker is installed on the 10kV distribution line branches, capable of reducing the power outage area. With a clear break point, it serves as a disconnecting switch, providing 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 features such as economy, ease of operation, and strong adaptability to outdoor environments. It is widely used in 10kV power distribution lines and transformers for primary side protection and equipment commissioning and disconnection operations, achieving widespread application.
