Introduction of 51200 Fuse

A 51200 fuse is a type of specialty fuse used in a variety of industries. It is designed to provide reliable protection against short circuits, overloads, and other electrical dangers. The 51200 fuse offers many advantages, including low operating current, excellent thermal protection, high electrical conductivity, and high breaking capacity. In addition, it has a long service life and low manufacturing costs. This makes it an ideal solution for many applications.

Applications of 51200 Fuse

The 51200 fuse is suitable for a wide range of applications, including battery protection, circuit protection, transformer protection, protection of photovoltaic installation, and total overload protection. This type of fuse is also used in motor starters, electric motors, generators, automotive electronics, lighting controllers, power supplies, transformers, and solar PV systems. The 51200 fuse is also ideal for applications where surge protection and overvoltage protection are required.

Working Principle of 51200 Fuse

The 51200 fuse uses a hollow-tube, zinc oxide varistor element to control the current. This element offers reliable protection against overcurrent, short circuits, and overvoltage. The fuse has two main functioning parts: the power element and the protective element. The power element is composed of a ceramic sleeve, a cylindrical core, and a nitrogen-filled chamber. The protective element is composed of a zinc oxide core, a spiral spring, a diode, and a voltage-limiting resistor.When an overvoltage or overcurrent situation occurs, the zinc oxide core of the fuse will activate and reduce the amount of current. The spiral spring will then compress, causing the voltage-limiting resistor to reduce the amount of current flowing in the circuit, thus protecting the electrical system from damage. In addition, the nitrogen-filled chamber of the power element will help dissipate heat, further protecting the circuit from overloading or overheating.The 51200 fuse is available in a wide range of current ratings, ranging from 0.5 to 10 A. The maximum instantaneous voltage rating is 2200 V. This fuse is designed for use with UL standards and conforms to IEC 60269-2 and VDE standards. This type of fuse offers reliable protection and can be mounted in any orientation.

Conclusion

The 51200 fuse is a reliable, low-cost fuse that is suitable for many applications. It is designed with a hollow-tube, zinc oxide varistor element that offers reliable protection against overcurrent, short circuits, and overvoltage. The fuse can be used in a wide range of electrical applications, including battery protection, motor starters, electric motors, generators, automotive electronics, lighting controllers, power supplies, and transformers. This specialty fuse has a long service life and is available in a wide range of current ratings.
