0218.200MRET1P

Fuses are a type of widely used protective device in the circuit, which is generally composed of two parts: conductor and fuse element. 0218.200MRET1P series fuse is a kind of fast acting single pole fuse, specially designed for high rated current applications and covers rated current of 40A to 75A. It features high interrupting and low voltage drop characteristics.

Applications

0218.200MRET1P fuse is ideal for use in a wide range of power system applications, such as air conditioners, refrigerators, washing machines, electric fans. It also can be used as a primary protection for electric equipment such as automotive circuits, electronic circuits, household appliances and those high inrush and general-purpose applications.

Working Principle

The working principle of the 0218.200MRET1P fuse is evaluated by an internal thermal element and an arcing mechanism combination. When the current passing through the fuse exceeds the rated current, the thermal device will absorb the heat, thus cause the internal temperature to rise and melts the fuse element. At same time, kinetic energy inside the fuse, such as the particles’ energy and vibration energy, will make the internal arc easier to run. After fusing current, the arcing current will form a bridge between the internal repaired parts. This bridge is called the arc trace, which will ease the cold clearing time and reduce the temperature caused by cold clearing.

Advantages

0218.200MRET1P fuses offer advantages of superior arc quenching characteristics, high precision in current ratings, lower voltage drop, lightning protection feature, low contact voltage resistance and environment friendly outcome.

Conclusion

0218.200MRET1P fuse is a fast-acting fuse with high current ratings, specially designed for a wide range of applications. It features excellent interrupting capacity, low voltage drop, high precision in current ratings, and lightning protection feature. It is also an environment friendly fuse with low contact voltage resistance.
