A fall-type circuit breaker is a commonly used short-circuit protection switch for 10kV distribution lines and transformer substations.

Falling fuse breakers are installed on the 10kV distribution line branches, which can reduce the scope of power outages. With a distinct disconnection point, they offer the function of an isolation switch, 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 efficiency, ease of operation, and strong adaptability to outdoor environments. It is widely used in 10kV power distribution lines and primary sides of distribution transformers for protection and equipment commissioning/cutting operations, and has gained widespread popularity.
