0215012.MXK20P Application in the Fuses Field and Working Principle

The 0215012.MXK20P is a Midget Fuse (MK). Midget fuses are used for protection in industrial, residential, commercial and motor control applications. It is designed for general purpose, panel board and motor protection. It has a high interrupting rating and is UL and CSA listed.

Application

The 0215012.MXK20P is primarily used in branch circuit applications, such as controlling non-linear loads in motor controls, panelboards, switchboards and general purpose circuits. It is well suited to industrial installations, where higher interrupting rating and low voltage standby rated current capabilities are required. It is also ideal for general purpose and residential applications, providing selective coordination and overload protection.

Working Principle

The 0215012.MXK20P works by sensing the current through the circuit and breaking it off when it rises to a critical point. This functions by melting a thin metal strip when the current passes through it. The high heat generated causes the metal to melt which then causes an interruption in the circuit. This prevents damage to the circuit by tripping it at the moment of potential harm. The fuse also has the ability to quickly react and reset when the user switches off the power.

In a sealed environment, when current passes through the thin metal strip, an arc is formed instead of immediate interruption. The arc cools down once the current is dropped and the contact area of the metal strip is cooled by the arc. This ensures complete disconnection of the contact points and avoids any sparking or arcing.

Conclusion

0215012.MXK20P Fuse is a versatile device that can be used for a wide range of applications, ranging from industrial to general purpose. It is designed for maximum protection and safety purposes in residential or commercial, motor control and panel board applications. The working principle of the fuse utilizes a thin metal strip that melts when the current passes through it. This causes an interruption to the circuit, preventing any damage. When the current is dropped, the arc cools down and the contact area of the metal strip is cooled by this process, ensuring complete disconnection and preventing any sparking or arcing.
