0443004.DR

Fuses

The 0443004.DR is a type of fuse designed for the automotive, industrial, and power distribution sectors. It is a current limiting device designed to protect circuits from overcurrent and short-circuit conditions. The fuse works by using a continuous metal strip that runs through it in a loop. When the current load on the circuit rises above its designed threshold, the metal strip melts, breaking the circuit and discharging the current safely. The 0443004.DR is a fast-acting fuse that provides circuit protection through its high rupture current rating.

Design

The 0443004.DR comes with a range of features designed for the automotive industry. It is a single-pole, dual-element, current-limiting fuse with a small physical footprint. It is UL-listed, and has high performance in terms of thermal shock, vibration, and salt-spray resistance. The fuse also offers high reliability due to its low thermal and contact resistance. It has a silver-plated copper contact system, which increases its electrical stability by a large margin.

Application Field and Working Principle

The 0443004.DR is designed for use in automotive, industrial, and power distribution applications. It is commonly used in applications that require current-limiting protection, such as motor drives, welding equipment, and air conditioners. It is also suitable for use in sensitive electronic circuits such as communications systems and telecommunication networks. The fuse works by using a continuous metal strip that runs through it in a loop. When the current load on the circuit rises above its designed threshold, the metal strip melts, breaking the circuit and discharging the current safely. The fuse is designed to react quickly in order to protect sensitive devices from permanent damage due to fault currents. It is designed to prevent overcurrent conditions but still allows normal currents to pass through.

Specification

The 0443004.DR has a voltage rating of 48V DC, and a current rating of 30A. The fuse operates within a temperature range of -40°C to 85°C. It has a fuse holder, and the fuse element has a dimension of 17x25 mm. It comes with a shatterproof transparent cover and a visual indicator for determining if the fuse has melted or not. The maximum breaking capacity of the fuse is 50A at the rated voltage, allowing it to effectively protect circuits from short-circuit faults. The 00443004.DR is designed to meet all relevant safety standards.

Conclusion

The 0443004.DR is a fast-acting fuse designed for automotive, industrial, and power distribution applications. It offers high performance with features such as its small physical footprint, silver-plated copper contacts, and shatterproof transparent cover. It has a voltage rating of 48V DC and a current rating of 30A, and is designed to react quickly in order to protect sensitive devices from permanent damage. The 00443004.DR is UL-listed, and meets all relevant safety standards.
