Overview
Description:

The fuse is composed of two parts: the base and the arc extinguishing device. The lower end of the arc extinguishing tube is equipped with a spring bracket that can rotate, and the fuse is always in tension to ensure the self-locking of the arc extinguishing tube in the closing position.

In the overload or short circuit of the line and the transformer, the fuse is blown, the fuse is quickly extracted from the arc extinguishing tube, and the arc extinguishing tube is designed to solve the contradiction of breaking the current on the same fuse by the stepwise exhaust type.
