KLLU750.X Application Field and Working Principle

KLLU750.X is a type of electrical, specialty fuse. This product is designed for special applications that require either very low voltage drop or large overload current protection. It is ideal for motor circuits, particularly on equipment where the circuit must remain energized even during short overloads or where the protection of other components is needed.

Overview of KLLU750.X Electrical Fuse

This electrical fuse is rated 250V AC/220V DC and features a manual reset design with two types of mounting. It also has an innovative double roving fuse element with copper-glass mud. The fuse element is laser-etched with reference markings for safe use.

KLLU750.X provides maximum current interruption capabilities and allows for a fast response time. Its design also enables a very low voltage drop, reducing power loss and energy waste. Additionally, its manual reset design makes it suitable for motor circuits where the circuit can remain energized even during short overloads.

Application Fields of KLLU750.X Electrical Fuse

The KLLU750.X electrical fuse is mainly used for the protection of motor circuits and associated wiring. It offers reliable overload protection by preventing short-circuit currents from damaging the motor equipment or surrounding wiring. It can be used in applications where the circuit must remain energized even during short overloads and where the protection of other components is paramount.

This fuse is also used in low-voltage industrial applications such as power distribution, lighting networks, and panels. It is suitable for the protection of industrial machines and home appliances, as well as in main switch gear and protection boards. As a UL-approved product, KLLU750.X can also be used in numerous applications areas such as railway systems, electric vehicles, medical equipment, and IT systems.

Working Principle of KLLU750.X Electrical Fuse

When an overload or short circuit occurs in the motor circuit, the KLLU750.X electrical fuse will react almost immediately due to its fast response time. Its unique design enables a very low voltage drop, reducing power loss and energy waste. The fuse element is laser-etched with reference markings that indicate the maximum current it can contain.

When the current exceeds the fuses’ rating, the metal strip of the fuse element melts, which causes an interruption in the electric current supply. The fuse then has to be reset manually and replaced when the fault is fixed. This manual reset design makes it suitable for motor circuits where the circuit can remain energized even during short overloads. This allows for a quick response in the event of an overload.

Conclusion

KLLU750.X electrical fuse is a specialized product designed for the protection of motor circuits and associated wiring. Its innovative design enables a low voltage drop and fast response time, making it suitable for a wide range of industrial applications. Its manual reset design also ensures that the motor circuit can remain energized even during short overloads.
