Electrical, Specialty Fuses: 170M3395 Application Field and Working Principle

Electrical power is one of the most important source of energy that we use today, and the fuses are one of the important components used in these devices for protecting them from overcurrents or short circuits. The 170M3395 is one of the specialty fuses used in many applications to protect components and to ensure their normal operation. In this article, we will discuss the application field and working principle of this fuse.

The 170M3395 is a time-delay class RK1 fuse, which is designed for protection of electrical equipment such as air conditioners, washing machines, refrigerators, and other home appliances. This fuse has an interrupting rating of up to 100A and a voltage rating of up to 600V. The average time-delay of this fuse is 0.9 sec and it has a minimum melting I2t of 10A2 seconds.

The time delay feature of the 170M3395 provides additional protection for equipment that is subject to high inrush currents or high overloads, as well as periodical current that can cause instantaneous fuse blowing. This fuse type is well-suited for applications with a low trip setting or a steep overload curve, thus providing added protection. Moreover, the use of this kind of fuse is beneficial for motor applications, as it can provide additional time for the motor winding to cool during an overload.

In addition to this, the 170M3395 is also designed with a low voltage drop feature. This feature allows the fuse to carry larger than normal current without overheating, thus providing more protection and improving efficiency. It also helps reduce the burden on the circuit and prevents its electrical components from damage.

The working principle of this type of fuse is relatively simple. When the current through it exceeds certain limits, the element inside the fuse reaches its melting point, thereby triggering the melting of an internal bridge-like structure that links two conductive elements in the fuse. This will cause the fuse to blow, thus interrupting the current flow.

The 170M3395 can be used in residential, commercial, and industrial applications such as over-current protection of motors, air conditioning systems, washers, and refrigerators. It is suitable for use in single and three-phase systems. It is also widely used in protection of sensitive circuits such as fire alarm systems, medical eqiuipments, data processing systems, telecommunication devices, and other devices with a narrow overload response requirement.

The 170M3395 time-delay class RK1 fuse is designed for over-current protection of electrical equipment, offering a range of protection from over-currents and high inrush current. Its low voltage drop and fast-acting feature make it suitable for motor applications, while its high interrupting and voltage ratings make it ideal for residential as well as commercial and industrial applications.
