The RW12 - 15/200A Drop - Out Fuse is a key component in 15kV power distribution systems, It is suitable for the voltage range of 15 - 36 kV and can also cover the 33 kV voltage level.rated at 200A. Primarily serving as a protective device, it effectively safeguards electrical circuits, transformers, and other equipment from overloads and short - circuit faults.
Structurally, it features an insulating support, a fuse tube, and contact assemblies. The fuse tube houses the melt element, which is made of a specialized alloy. When abnormal currents occur, the melt element quickly melts, generating an arc. The design of the fuse tube enables efficient arc extinction, after which the tube drops open, visibly disconnecting the faulty section from the grid. This visual indication simplifies fault detection for maintenance personnel.
This fuse is easy to install and operate, making it a practical choice for outdoor substations, rural power grids, and small - to - medium - sized industrial applications. Its reliable performance and cost - effectiveness contribute to stable and safe power distribution.
