Load Switch Explained | Functions, Fuse Integration & vs Isolator Differences

What is a Load Switch? A load switch is a control device equipped with a simple arc-extinguishing mechanism, capable of opening and closing circuits under load. It can interrupt a certain level of load current and overload current, but cannot interrupt short-circuit current. Therefore, it must be us

10kV Expulsion-Type Fuse | Structure, Selection & Installation Safety Guide

Fuses are connected in series in a circuit. When the current through the fuse element is less than or equal to its rated current, the element will not melt. Only when the current exceeds the rated value and reaches the fusing current will the element melt. When a short circuit (or overload) current
