3JQ 4-R

3JQ 4-R Application Field and Working Principle

A 3JQ 4-R Class Fuse is an over-current protection device used to protect electrical circuits from damage caused by excess current, misuse, and other improper actions. This fuse is designed to resist large overloads, short-circuits, thermal and other overloads by interrupting the circuits. The 3JQ 4-R Class Fuse is used in residential, commercial and industrial applications, including motors, HVAC systems, lighting systems and heating systems.

Working Principle of 3JQ 4-R Class Fuse

The working principle of the 3JQ 4-R Class Fuse is based on the Joule effect. This effect occurs when two materials, which have different electrical resistance, come into contact with each other. When the different materials are connected, the electrical current that flows through them causes heat to be released. As the amount of current passing through the fuse increases, so does the amount of heat that is generated. When the amount of heat generated exceeds the maximum rating of the fuse, copper or brass elements inside the fuse melt, separating the circuit and disconnecting the power supply.

Features of 3JQ 4-R Class Fuse

The 3JQ 4-R Class Fuse is designed to provide superior protection against current fluctuation and short circuits, and to resist high temperatures and other overloads. The 3JQ 4-R fuse is manufactured from the highest quality materials, ensuring reliable protection against faulty wiring. It has a low voltage drop across the fuse, which improves the performance of the equipment and reduces the risk of power loss. The 3JQ 4-R Class Fuse has a clear indication of the fuse rating, making it easy to identify and select the correct fuse for the application. It also features easy installation and replaceability; no special tools or test equipment are required to install or change the fuse.

Conclusion

The 3JQ 4-R Class Fuse is a reliable and cost-effective over-current protection device for residential, commercial and industrial applications. The fuse has a Joule effect working principle, which allows it to interrupt the circuit in the event of excess current, short circuits and thermal overloads. It is manufactured with high-quality materials and has a low voltage drop, making it a reliable choice for protecting electrical circuits.
