170M3985

Introduction

170M3985 is a specialty fuse produced by the Eaton Bussmann Division. It is designed for circuit protection in various applications such as electric cars, battery-powered industrial equipment, and high-voltage AC motors. The product has a current rating of up to 2000A and voltage rating of up to 440VAC or 690VDC. It is UL Recognized, CSA-certified, and meets other safety and certification standards. In addition, the product has a high interrupting current rating and is compliant with industry and automotive standards.

Application Field

The 170M3985 fuse is primarily designed to protect inrush currents in electric cars, battery-powered industrial equipment, and high-voltage AC motors. The product is also suitable for other high-power circuits that require protection from short circuits and over-voltage. It is ideal for use in applications where bulk and high PD (power dissipation) are not a concern and where space is limited. The fuse is also suitable for DC loads, and provides fast response time to fault currents for reliable protection.

Working Principle

The 170M3985 fuses operate on a heat-conducting principle. The fuse element consists of a current carrying conductor, with a fusing link, surrounded by a thermal insulation material. When the current through the conductor exceeds the rated current of the fuse, the fusing link will become heated and begin to evaporate until it eventually opens the circuit. The evaporated material is transferred onto an absorbent pad to stop further heat conduction and complete the fusing process. Additionally, the product self-resets and can be used multiple times after the overcurrent condition has been removed.

Benefits

The 170M3985 fuse has a number of benefits. It provides fast protection of electric circuits against short circuit and over-voltage inrush currents. It is lightweight and compact, making it suitable for use in tight spaces. It is also safe and reliable, meeting industry and automotive safety standards. In addition, it is easy to install and replace when needed.

Conclusion

The170M3985 is a specialty fuse that is suitable for use in electric cars, battery-powered industrial equipment, and high-voltage AC motors. It has a current rating of up to 2000A and voltage rating of up to 440VAC or 690VDC. The product operates on a heat-conducting principle, with the fusing link becoming heated and evaporating if the current through the conductor exceeds the rated current of the fuse. It is lightweight and compact, providing fast protection of electric circuits against short circuit and over-voltage. Additionally, the product has a number of safety certifications and is self-resetting.
