Introduction:

3JS 750 is a miniature type bit space fuse. It is primarily used as MCB, RCBO, isolator, residual current device, lighting contactor or starter, and can also act as a safety fuse in industrial electrical equipment. The 3JS 750 has a small size, fast installation and a reliable structure that makes it popular in many residential and industrial applications, such as: lighting, air conditioners, TV sets and other domestic electrical products that require fast switching. It’s considered as a modern and economical protection system for controlling the electrical current.

Working Principle:

The 3JS 750 fuse works by measuring the mechanical starting torque of the operating mechanism. When the current is too high, the current passes through the 3JS 750 wire, resulting in the temperature of the 2 JS 750 rising, causing the fuse wire to become inaccessible. The 3JS 750 will then cut off the current, which will protect the device from overloading.

Application Fields:

The 3JS 750 fuse is suitable for 220V AC electrical equipment. It is widely used in industrial electrical products, such as power supplies, air conditioning machines, refrigeration machines, TV sets, washing machines, and circuit breakers, as well as domestic electrical products, such as lighting, and so on. It is also popular in many residential and industrial applications for having a reliable structure and fast switching.

The common applications of 3JS 750 fuses includes protecting transformers, motors, circuit breakers, power supplies, and other electronic circuits. It can also be used in residential electrical systems for protection against over current, over temperature, and short circuit.

The 3JS 750 fuse is also an ideal protection device for industrial control systems. It can protect industrial equipment from overload and over temperature, and help extend the service life of the equipment. It is essential in many applications in the industrial field.

Conclusion:

The 3JS 750 fuse is an economical and reliable method of controlling current in various electrical applications. Due to its small size and fast installation, it is popular in many residential and industrial applications. It is suitable for 220V AC electrical equipment and works by measuring the mechanical starting torque of the operating mechanism.

It can protect transformers, motors, circuit breakers, power supplies, and other electronic circuits, as well as residential electrical systems from over current, over temperature, and short circuit. The 3JS 750 is also an ideal protection device for industrial control systems. All in all, it is an important component for any electrical systems.
