Fuses are a type of critical component often found in a variety of applications and systems. In order to ensure the safe and efficient operation of electrical equipment, fuses play an important role in providing fault protection and power regulation. The MJS 500-R is a common type of fuse that is used in a variety of different applications. This article will discuss the functions and properties of the MJS 500-R fuse and its application field. We will also discuss the principles of its working.

Features and Properties of the MJS 500-R Fuse

The MJS 500-R fuse is an standard 2-point fuse and has a voltage rating of 500V. It is a standard size for industrial applications and is RoHS compliant. In some cases the 500-R can be replaced with a higher rating fuse, such as the 600V type, when the current rating and voltage of the system require it. The 500-R has a breaking capacity of 50kA and an interrupting rating of 60kA when AC currents are used. For DC current, the interrupting rating is 75kA. The contact spacing within the fuse is 0.375”, which allows it to be used in a variety of different applications and systems.

Applications of the MJS 500-R Fuse

The MJS 500-R is commonly used in a variety of different applications. It can be found in industrial control panels, motor starters, and motor control centers. It can also be used in emergency lighting systems and is often used as back-up for motor overload protection. Additionally, the 500-R is often used in power circuit breakers, transformers, and other high voltage applications where fault protection is needed. The MJS 500-R is also commonly used in the automotive and transportation industries, and is typically installed in the starting circuit of vehicles.

Working Principle of the MJS 500-R Fuse

The MJS 500-R fuse is designed to operate when the electrical current that is passing through it exceeds the rated value. The fuse will open when the current exceeds the rated value, which prevents damage to the equipment in the event of an overload or surge. The current that passes through the fuse is converted into heat, which then melts the metal alloy ending of the fuse. This breaks the circuit and prevents any further current from passing through. The fuse can then be replaced once the overloaded current has passed. If the voltage or current exceed the limits of the fuse, the fuse will be permanently damaged.

Conclusion

The MJS 500-R is a commonly used fuse in a variety of different applications. The fuse has a voltage rating of 500V and can be used for both AC and DC current. It is a common size for industrial applications and is RoHS compliant. The MJS 500-R can be found in industrial control panels, motor starters, emergency lighting systems, power circuit breakers, and more. The working principle of the fuse is that it will open when the current that passes through it exceeds the rated value. The fuse is then replaced once the overloaded current has passed. The MJS 500-R is an important component for providing protection and regulation of electrical systems.
