0298250.ZXB application field and working principle

The ZXB series fuse is an AC sodium fuse and is a type of time-delay fuse. It is the ideal power overload and short-circuit protection for AC power systems, and is suitable for large machines, oil-immersed transformers, reactors, etc. The product has the advantage of high breaking capacity.

The time-delay fuse is a fuse that can play the role of power overload protection and short-circuit protection in the power system. It is mainly used to protect electronic devices such as transformers and electric motors, to prevent an unbalanced AC circuit from overloading or a short circuit, or to blow up the fuse when a fault occurs, and to cut off the current in the power circuit to avoid any damage to the power system. In addition, because the blowing time of the fuse is much longer than that of other fuses in the circuit, it can reduce the impact of short-circuit current to the device.

Working principle

The ZXB series fuse uses a melting wire as its heating element, and the melting wire is made of a special alloy with a high melting point. When an overload or short circuit occurs, the current temperature rises rapidly and the melting wire melts, which then disconnects the circuit and the fuse blows.

Application field

The ZXB series fuse can be widely used in the protection of power distribution transformers, reactors, and various large industrial and mining equipment management with AC power supply. It can also be used to reduce the poor contact caused by AC current and protect sensitive electronic products, such as computers and communication equipment. It is suitable for protecting current distribution systems in power distribution systems, providing comprehensive protection such as overload and short circuit protection.

The ZXB series fuse has three major advantages: high breaking capacity, high precision, and excellent overload protection. With a breaking capacity of up to 20000A and a breaking characteristics curve of up to 60000A, it performs far better than the traditional ACcurrents fuse. It can avoid repeated fusing due to wrong current, short circuit current and overload current.
