Other Types Of Drop-out Fuses In Use

This type of 33kv fuse is mainly used to protect power transformers and general electrical equipment. The breaking current range of the backup cover drop out fuse refers to the range from overload current greater than 4 to 7 times the rated current to a larger breaking current. This type of drop fuse is often used in series with a contactor. When the overload current of the drop fuse cutout is less than 4 to 7 times the rated current, the contactor will realize the breaking protection. It is mainly used to protect motors.

With the needs of industrial development, special drop out expulsion fuse suitable for various requirements are also manufactured, such as electronic drop out fuse 22kv, thermal drop out fuse 33kv and self-resetting drop out fuse cut out.
