Introduction

The 0677.630DRT4 is a model of fuse produced by one of the most influential and renowned fuse suppliers in the automotive industry, the DRT4. The fuse is used in the automotive market and is classified as part of the fuses family. This article will provide an in-depth explanation of the 0677.630DRT4, including its application field, working principle and features.

Application Field

The 0677.630DRT4 belongs to the DRT4 family of automotive fuses and is categorized as a mid-range direct replacement fuses. This type of fuse is specifically designed to be used in the automotive industry as it provides a number of features that are useful for automotive applications. These features include a high breaking capacity, low curve ride-through ability, effective current limitation and a fast acting fuse. The 0677.630DRT4 can be used for a variety of purposes in the automotive market, such as for the protection of the vehicle’s electronic and electrical components, circuits and wires, as well as for power distribution. This type of fuse is especially useful in applications where a fast acting and reliable fuse is required.

Working Principle

The 0677.630DRT4 fuse follows a similar working principle to other types of fuses. The fuse works by limiting the amount of current that passes through it. This is achieved by using a metal strip that is located inside the fuse. As the current passing through the fuse increases, the metal strip is heated and eventually melts, thus breaking the circuit and preventing any further current from passing through it. This is what allows the 0677.630DRT4 to act as an effective over-current protection device.

Features

The 0677.630DRT4 offers a number of features that make it desirable for many automotive applications. Firstly, it has a high breaking capacity of up to 1500A at 125V. This ensures that it can handle large amounts of overload current without having to be repaired or replaced after each overload. Secondly, it has a low curve ride-through ability which allows it to ride through short circuit overloads without having to blow too soon. This makes the 0677.630DRT4 an ideal choice for applications where it is expected that there may be short circuit overloads. Thirdly, it is designed to provide effective current limitation which helps it to protect other components from being damaged by over-current. Fourthly, the 0677.630DRT4 fuse is fast acting, meaning that it responds quickly to short circuit overloads and other types of over-current conditions. This makes it a desirable choice for those applications where a fast-responding fuse is necessary.

Conclusion

In conclusion, the 0677.630DRT4 is a mid-range direct replacement fuse in the DRT4 family of automotive fuses. It is designed for the automotive market and has many features that make it desirable for the protection of vehicle components, wires and circuits. Its high breaking capacity, low curve ride-through ability, effective current limitation and fast acting fuse contribute to making the 0677.630DRT4 an excellent choice for use in many automotive applications.
