ABB WBP-20 HV WBP type Fuse link high-voltage backup fuses

WBP-20: Rated voltage 24kV, diameter about 23mm, length about 310mm.

ABB WBP-20 HV WBP type Fuse link is a fuse used in medium and high voltage power systems. It is mainly used to protect voltage transformers from short circuit faults. The following is a detailed introduction:

Basic parameters

Rated voltage: 24kV, suitable for 24kV power systems, can work normally and provide reliable protection at this voltage.

Size: diameter is about 23mm, length is about 310mm.

Rated current: usually different specifications such as 0.5A - 4A are available to meet different circuit load requirements.

Breaking capacity: up to 120kA, it can quickly cut off the circuit in the event of short circuit and other faults to ensure the safety of equipment and systems.

Features and advantages

Current limiting function: it can quickly limit the current when a short circuit fault occurs, effectively protect electrical equipment, and reduce the impact of the fault on the system.

Thermal release striker: the integrated thermal release striker makes the action of the fuse related to the temperature, has overload protection function, and can significantly reduce the fuse temperature during the fusing process, improving the safety of use.

Strong compatibility: compatible with ABB's TJC and TDC voltage transformers, it can be well adapted to related equipment to ensure the overall performance of the system.

Wide application: Due to its small size and high performance, it can be used in various switchgears, including explosion-proof switchgears, and is suitable for a variety of medium and high voltage power system scenarios.
