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.
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
Overcurrent Protection
Drop out Fuse Application
Distribution Transformers
Drop-out fuses are commonly installed on the primary side of distribution transformers. These drop out type fuses provide overcurrent protection to the transformer against faults such as short circuits and overloads. In the event of a fault, the drop out fuse in transformer opens, isolating the transformer from the faulted section of the circuit.
