ABB HV WBP type Fuse link high-voltage backup fuses

WBP type:

Application: Effective protection of circuits in the event of voltage transformer failure.

Voltage and Current: Rated voltage 7.2-40.5kV, rated current 0.5-4A.

Features: Compared with the previous generation of products, it adopts a porcelain tube design, which is more durable and easy to operate, and is compatible with ABB's TJC and TDC type voltage transformers.

ABB HV WBP type Fuse link is a high-voltage current-limiting backup fuse, mainly used to protect voltage transformers from short-circuit faults. The following is a related introduction:

Features and applications

It has a current-limiting function, which can quickly limit the current in the event of a short-circuit fault to protect electrical equipment.

The integrated thermal release striker makes the action of the fuse temperature-related, and has an overload point design, which can significantly reduce the fuse temperature during the fusing process.

It has a high breaking capacity of up to 120kA, suitable for medium and high voltage power systems of 7.2-40.5kV, and can be used in various switchgears, including explosion-proof switchgears, and is compatible with ABB's TJC and TDC type voltage transformers.
