0TOO009.Z

0TOO009.Z Application Field and Working Principle

The 0TOO009.Z is rating type fuse specifically designed for AC and DC high-voltage short-circuit protection. It is a high-voltage short-circuit protection device characterized by high breaking capacity, long service life, special housing circuitry, quick response to fault current, precise operation, and low internal temperature rise.

The application of the 0TOO009.Z fuse mainly focused on power plants, power grids, electronic transformers, wind turbines and other high voltage electrical systems. The 0TOO009.Z fuse is divided into 0P, 0M and 0D three types. 0P type is suitable for applications with adjustable short-circuit protection level, 0M type is suitable for applications with adjustable short-circuit protection level and changeable on-state current, and 0D type is suitable for adjustable short-circuit protection level, changeable on-state current and different minimum off-state current levels.

The working principle of the 0TOO009.Z fuse is based on its melting and arc extinguishing characteristics. When the fuse is working, the fault current will produce heating. When the current reaches the rated maximum current, the internal temperature of the fuse will exceed the specific melting point and the fuse link will melt. In the meantime, the surrounding air is also heated to create an arc inside the fuse blades and automatically drive the arc extinguishing part of the contact point. This will separate the two contact points of the fuse. As a result, the contacts will disconnect and the circuit will be broken, achieving short circuit protection.

The 0TOO009.Z fuse has many advantages, such as high breaking capacity, short response time, excellent temperature stability and superior reliability. It is widely used in various fields of electric power industry due to its reliable performance, excellent insulation performance and long service life. It is the preferred choice for high voltage short circuit protection in the industry.
