How to choose the correct fuse to protect the transformer?Let Wenzhou Best Imp. &Exp. Co., Ltd tell you.
The current sensing fuse link can sense secondary faults, excessive load currents and transformer faults, not like dual sensing fuse https://www.besthvelectric.com/transformer-components/fuse/dual-sensing-fuse.html, it can't sense transformer oil temperature. Because the current sensing Bay-O-Net fuse link only monitors current, not temperature,they will expulse according to its Time-Current Curve (TCC), this is the origin of its other name, expulsion fuse.
