Fuses

0678D5000-02 application field and working principle

0678D5000-02 is a type of fuse, a device that protects electrical circuits from excessive current. It is mainly used in low-voltage DC circuits. The fuse is composed of the ignition body, the internal core, the protective housing, the conductor connection part, etc. It has various advantages such as safe explosion, small size, light weight, easy installation, reliable and accurate operation, and long operating life.

The internal core of 0678D5000-02 is composed of an electro-fuse wire. The wire is connected in series with the power line, and the resistance is very small when the normal current is applied. If the current is excessive, the fusible wire can be burned by more than the allowable amount, breaking the current, and the fuse can be quickly cut off to avoid equipment damage caused by excessive current for a long time.

0678D5000-02 is suitable for low-voltage DC circuits, and its working principle is to cut off excessive current. Its features are better protection performance, long-term stable current, no excessive current leakage, small energy consumption, adaptability to harsh environments and strong overload capacity. Its function is mainly to connect the load in series with the circuit, accurately detect the current in the circuit, and have the function of disconnecting the circuit when the current exceeds the rated value.

The rated current of 0678D5000-02 is 5000A, and its rated voltage is 48V. Its maximum short-circuit current tolerance is ≥200KA, the rated current breaking capacity is ≥150A, and the maximum impact current is 10KA. In terms of operating temperature range and temperature compensation range, it is -54~+155℃ (-67~+311℉), -55~+85℃ (-67~+185℉)

In summary, 0678D5000-02 is a type of fuse mainly used in low-voltage DC circuit protection. Its working principle is to cut off the excessive current by breaking the fusible wire when it exceeds the rated value. Its various characteristics and performance advantages make it an ideal choice for circuit protection.
