Fuses

Fuses are electrical protection devices used to protect electrical circuits, wires and devices from excessive current. 0673.800DRT4 is a type of fuse specifically designed for use in DC applications. This article discusses the application field and working principle of this special type of fuse.

Application Field

The 0673.800DRT4 fuse is designed for use in direct current (DC) applications. It is UL listed for a maximum voltage of 48 volts and can handle currents of up to 200 Amps. This makes it ideal for use in many higher power DC applications, such as electric vehicles, industrial and commercial equipment, and solar power systems. It is also suitable for use in automotive, computer, telecommunications, and other electronic circuits.

Working Principle

The 0673.800DRT4 fuse is a current-limiting fuse. This means it is designed to limit the amount of current flow when an overload or short circuit occurs, preventing damage from excessive or unexpected current. When there is an overload or short circuit, the fuse will first reduce the current flow to a safe level to protect the circuit. After the fault is removed, the fuse will automatically reset, allowing the normal circuit operations to resume.

The 0673.800DRT4 fuse is also temperature-sensitive. This means that when the internal temperature of the fuse exceeds a preset threshold, the fuse will open to break the circuit, protecting against overheating. The opening time of the fuse is designed to be fast enough to prevent serious damage to electrical components.

Another important feature of these special fuses is that they are low-profile, meaning they are designed to fit into tight spaces. They are also colour coded for easy identification. Depending on the exact model, these fuses may be designed to act either as time-delay or fast-acting fuses.

Conclusion

The 0673.800DRT4 fuses are designed for DC applications and are UL listed for up to 48 volts and 200 Amps. They are current-limiting and temperature-sensitive fuses, and are available in both time-delay and fast-acting versions. They are low-profile fuses with a colour coded body for easy identification, making them the perfect choice for a wide range of DC applications.
