0891020.NXS

0891020.NXS is a type of fuse, which is an extremely important element in the electrical circuit. Fuses protect the electrical circuit by automatically cutting the circuit when the current reaches an undesired or unsafe voltage. This type of fuse is commonly used within the high voltage industry, as it has a rated voltage up to 7500 V and a rated current up to 630A. Due to its high voltage capacity, 0891020.NXS can be used in various application fields, such as residential and industrial buildings, electric railway systems and buildings, photovoltaic systems, transformer installations, and wind turbines.

The 0891020.NXS is an indoor type fuse and it comes with a ceramic body and a protective cover. The case of the fuse is a solid, light yellow ceramic material, which is resistant to punctures or other mechanical shocks. The protective cap is a robust polymer material, designed to stop dust, moisture, and other contaminants from entering the contact area of the fuse. Both the case and cap are designed in compliance with IEC requirements, which provide enhanced protection for the fuse when in operation.

From a technical standpoint, the 0891020.NXS fuse works by allowing a predetermined amount of current to pass through it before the fuse trips the circuit. When the current flowing through the fuse exponentially exceeds the rated current, the fuse will respond to this sudden current surge and force the circuit to trip. Overload protection fuses, such as the 0891020.NXS, are designed to react quickly when the current surge exceeds the rated current, thus protecting the circuit from any further damage.

In summary, the 0891020.NXS is a type of high voltage fuse, which is commonly used within the high voltage industry. It has a rated voltage of up to 7500V and a rated current of up to 630A, making it suitable for various applications. The fuse operates on the principle that a predetermined amount of current can pass through it before the circuit trips. When the current surge exceeds the rated current, the fuse will quickly trip the circuit, thus protecting the circuit from any further damage.
