3JQ 1.5

Introduction

A fuse is a device designed to protect an electrical circuit from overcurrent or short circuiting or both, by creating an open circuit when either of these types of fault occur. With the advent of more sophisticated electronic and electrical equipment, protection devices have become more complex and specific to the application. Fuses have been around for a long time and came into existence in 1892, when Thomas Edison developed an early version of a fuse used in the first electric meters. Fuse designs have evolved significantly since then and when selecting a fuse for a given application, considerations must be taken into account, such as material selection, size, voltage and current rating, as well as features such as fast, slow, LP or HP ratings.

3JQ 1.5 Fuse Application Field and Working Principle

The 3JQ 1.5 fuse is designed for a variety of applications and is one of the most commonly used Fuses on the market. It is used in automobile, home appliance, electrical equipment, and audio and video equipment. This high-quality automotive fuse is designed to provide overload and short circuit protection. The fuse provides rapid-acting protection at various current levels, making it ideal for protecting electrical circuits in cars, trucks, audio systems and other automotive applications.

The 3JQ 1.5 fuse works on the principle of heat dissipation. When the current passing through the fuse reaches the maximum defined current threshold, the heat generated in the fuse melts the bimetallic element inside. This causes the bimetallic element to bend or open the contact between the two points of the fuse, thus breaking the circuit and preventing damage to the circuit elements. The fuse is designed to be self-resetting, so once the current has been reduced below the threshold, the bimetallic element can cool and reset, thus allowing the current to pass again.

Conclusion

The 3JQ1.5 fuse is a great solution for protecting electrical circuits from overcurrent and short-circuiting. Its heat dissipation based protection principle makes it ideal for automobile, home appliance, electrical equipment and audio and video equipment. Due to its size, voltage and current rating as well as features such as fast, slow, LP or HP ratings, it is now one of the most widely used fuses on the market.
