FLD-120 is a current limiting type fuses mainly applicable to short circuit protection of three-phase alternating current circuits. It is widely used in power substations, industrial and mining enterprises, housing construction and mobile power supplies. It plays an important role in protection of power facilities and electric equipment against overcurrent damage. Therefore, it is necessary to understand the main application fields and working principle of FLD-120.FLD-120 has wide application fields. It is mainly used in the short circuit protection of AC circuits, especially for three-phase AC circuits. It is suitable for power distribution system of industrial and mining enterprises, housing construction and mobile operations with AC frequency of 50Hz/60Hz, rated residual operating current less than 0.2times and other operational conditions.The main working principle of FLD-120 is that it will automatically open the circuit to cut off the power supply of the three-phase AC loop when the current of the power system is too large or exceeds the setting value.FLD-120 uses two forms of current limiting type fuses and non-current limiting type fuses. The former contains two fuses, in which the upper fuse is used for short circuit protection, and the lower fuse is used for long circuit protection. The working principle of the two forms of fuses is similar, that is, when a short circuit or overload occurs, the current will rise sharply and the fuse will be opened to cut off the power supply of the three-phase AC loop.The current limiting properties of FLD-120 fuses can provide higher short-circuit protection capacity than general-purpose air switch. It will produce expanding arc at the time of short-circuit. It can effectively restrain the expansion of the arc, inhibit the current rise and reduce the damage to the equipment caused by the short-circuit current.FLD-120 is a current limiting type fuse applicable to three-phase AC power distribution systems. It can provide effective protection against short circuit and overload. Its current limiting properties can effectively inhibit the current rise to reduce damage to electric equipment caused by short circuit current. It is an important element to ensure the safe operation of power facilities and electric equipment.
