Fuses provide an essential safety function that prevents electrical circuits from becoming overloaded. The 0672.250DRT4 fuse is one that can be used in a wide variety of applications due to its features.

The 0672.250DRT4 fuse is a time-delay, current-limiting fuse. This type of fuse is designed to allow a momentary overload current to flow for an extended time, up to the rated time-delay of the fuse. For instance, the 0672.250DRT4 has a time-delay of 10 seconds at 200% of the rated current. This allows the circuit to draw high levels of current for a short time before the fuse trips, unlike a standard non-time-delay fuse which will trip almost immediately upon an overload.

The 0672.250DRT4 can be used in high-energy circuits, such as those that experience higher than average inrush currents due to the turning on of motors. Inrush current is a high peak of current that is drawn when a motor turn on, and can be many times higher than the normal running current of the motor. The time-delay fuse can handle this spike of current and will trip if the current exceeds the rated amperage for more than the designated time-delay.

The fuse works by the construction of the device. The typical fuse consists of a metal strip, or wire, which is designed to heat up when a current is passed through it. As the metal heats, it melts, creating an interruption in the current flow. This interruption is the "trip" that we experience when a fuse blows.

The 0672.250DRT4 is a special type of fuse that utilizes a ceramic body to achieve its time-delay feature. The ceramic body is a special material that takes longer to heat up under the same current conditions as compared to a standard metal fuse. This slower heating allows more time for the current to flow before the fuse trips.

The 0672.250DRT4 can be used in a variety of applications where short-term, high-amperage surges are present. Examples include motor starters, electric pumps, centrifuges, elevators, welding equipment, and other similar equipment where short-term peak currents are present.

The 0672.250DRT4 fuse offers many advantages over standard non-time-delay fuses, including higher breaking capacity, improved inrush current handling, and longer life. It is an ideal solution for applications that require current protection from short-term overloads.
