0318.375H Fuses: Application Field and Working Principle

Fuses are an important form of electrical and electronic protection and are widely used in residential, commercial or industrial applications. The 0.318.375H fuses are well-known in the market since they provide the highest reliability and safety against short circuits and overcurrents.

Application Field

The 0318.375H fuse is designed for special disconnecting switches, branch circuit switches, and local disconnects. It has UL listed ratings for short time current ratings up to 100,000 amperes. This fuse is especially recommended for high-current applications in medium voltage circuits. Additionally, this fuse is suitable for motor control, medium-sized drill motors, clean-consuming loads, power tools, and related devices.

Working Principle

The 0318.375H fuse has a specifically designed arc extinguishing device that separates the contacts of the fuses when an overcurrent is detected. In a typical arrangement, the fuse is connected between two lines so that when an overcurrent is detected, the fuse will melt and create an arc between its contacts. The arc extinguishing device quickly quenches the arc, ensuring the interruption of the current flow.The 0318.375H fuse is constructed with a series of electrodes connected in parallel and acting as the electric current-controlling member. The contacts are made of silver or silver alloy plated and sealed with a ceramic covering. This particular model features a resistance of 10 ohms and an arc voltage of 2 volts.

Design Features

The 0318.375H fuse has a number of design features not present in other models. It has two terminals which are connected together with an insulating material, ensuring mechanical stability and electrical insulation. Additionally, the portable and reusable fuse carrier assists the user in installing and handling the fuse. More importantly, each fuse is manufactured with a unique copper alloy that is fireproof; this ensures that the fuse is not affected by fire, smoke, or other environmental hazards that may cause it to fail. The fuse also features an ultrasonic welded seal; this helps to improve performance by reducing the risk of arc flash and enhances the longevity of the fuse.

Conclusion

The 0318.375H fuse is designed for use in a variety of applications and is a reliable product that can provide optimal safety and protection. Its design features make it an optimal choice for high-current applications that require safety and reliability. This makes the fuse a great choice for industrial, residential, and commercial applications where the highest degree of protection is needed.
