A fall-type fuse 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 power outage area. With a distinct disconnection point, they function as isolation 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 economic features, ease of operation, and strong adaptability to outdoor environments. It is widely used in 10kV power distribution lines and transformers as a protection measure and for equipment commissioning and disconnection operations, and has become prevalent.
