DFJ-12

Specialty fuses are an important element of electrical system operation. DFJ-12 is a very important type of specialty fuse. This article will focus on its application field and working principle.

The DFJ-12 specialty fuse is designed to meet the requirements of power distribution networks and companies looking for an effective way to manage their electrical systems. It is a two-phase fuse with a rated voltage of 600V AC. The fuse is suitable for use in power distribution systems as a three-pole or four-pole fuse. It features a highly reliable and safe arc-quenching device that is capable of interrupting a current of up to 30 amperes in the event of an overload or short circuit. The fuse also provides an excellent degree of overload protection and is constructed from durable materials that reduce derailment and arcing.

The working principle of the DFJ-12 specialty fuse is based on the same principles as all other fuses in that, when an overload or short circuit occurs, the fuse will open to interrupt the current flow. This is achieved by the use of a metal strip or filament located inside the fuse. When an electrical overload or short circuit occurs, the heat produced by this excess current causes the metal strip or filament to melt, which in turn opens the circuit and interrupts the current. This helps to protect both the system and other components from damage.

The DFJ-12 specialty fuse is used in a variety of applications – from powering medical equipment and computer networks to providing back-up power for industrial, commercial, and residential purposes. It is designed to withstand a wide range of temperatures and can be used in both indoor and outdoor environments. It is also designed to maintain its integrity even when its contacts are subjected to drastic temperature changes or vibrations.

The DFJ-12 specialty fuse is highly reliable and is capable of protecting a wide range of electrical systems. It is a cost-effective way to maintain the safety of electrical systems and is widely used in a variety of industries and applications. Its application field is relatively vast and its working principle is quite simple and yet efficient.
