Drop Out Fuse Cutout Switch

The drop out fuse switch is an overcurrent protector, which is mainly composed of melt, fuse tube, and external fillers. When used, the drop out type fuse needs to be connected in series in the circuit to be protected. When the current of the protected circuit exceeds the specified value and after a certain period of time, the heat generated by the melt itself fuses the melt and disconnects the circuit, thus playing a protective role.

Drop out fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As short circuit and overcurrent protectors, they are one of the most commonly used protection devices. The drop out fuse element has inverse delay characteristics, that is, when the overload current is small, the fusing time is long; when the overload current is large, the fusing time is short.

Advantages of Drop Out Fuse Type Cutout Switch from YONGGUANG
Maintenance of Power Quality
By swiftly disconnecting faulty circuits, drop out fuse cutouts contribute to maintaining power quality in the distribution system. This is important for ensuring a stable and reliable power supply to consumers.

Easy Replacement
The design of drop out fuse cutouts allows for quick and easy replacement of fuses. This drop out fuse set facilitates efficient maintenance and reduces downtime during the replacement process, contributing to improved system reliability.

Overcurrent Protection
Drop out fuse cutouts protect electrical circuits from overcurrent conditions by interrupting the flow of current when the drop out fuse exceeds a predetermined level. This helps prevent damage to downstream equipment and ensures the safety of the overall system.
