Precision Engineering Of The Circuit Breaking Action Of Drop-out Fuses

The design of drop out fuse cut out often revolves around the response mechanism to overcurrent anomalies. The fuse's cross-section is measured by laser to match a predetermined current-time curve. When the current exceeds the rated value, the fuse melts rapidly, and the fuse tube falls off the support under gravity, creating a clear break, facilitating on-site personnel to identify the fault and perform replacement operations.

The components and mechanical structure of drop out fuse element have been meticulously engineered, and the geometry of connecting parts has been optimized to reduce contact resistance and minimize energy loss under normal conditions. In the event of a short circuit or abnormal current, the fuse and arc-extinguishing tube work together to extinguish the arc, and the cracked gas further suppresses the arc, thereby improving the arc extinguishing effect during circuit breaking.
