0452007.NRL application field and working principle

0452007.NRL is a type of fuse that is widely used in electrical systems for circuits with short-circuit and over-current protection. It is composed of a number of metal strands or a thin metal wire surrounded by a ceramic tube. Inside the tube is a bimetallic strip that warps when heated due to the increased current. When the current reaches a certain level, the bimetallic strip warps and the fuse opens the circuit to prevent electrical damage.

The application field of 0452007.NRL mainly includes the power transmission and distribution lines like low-voltage switchgear, motor control circuits and other related circuits. It is used to prevent systems from short circuits, over current and over voltage. Due to its compact size, it can be used in limited spaces. Meanwhile, this type of fuse also works great in damp and wet environments, providing reliable performance.

The working principle of the 0452007.NRL fuse mainly has two parts. Firstly, its bimetallic strip works as a temperature controller when current passes through. When the temperature rise exceeds the protection level, the strip will warp which results in the fuse blowing and breaking the connection. Then the melting wire in the metal strands creates an arc inside the tube, which breaks the electric flow. This ensures the contribution to short-circuit and over-current protection.

In conclusion, 0452007.NRL fuses are designed for short-circuit and over-current protection. They are widely used in the power transmission and distribution systems because of their small size and good performance in damp and wet environments. Their working principle relies on the bimetallic strip and melting wire in the metal strands, which create an arc to open the circuit.
