NH fuses are designed with a robust rectangular ceramic casing enclosed by a cover plate that includes a metal blade terminal at each end. Inside the casing, the fuse element is securely connected to these cover plate/blade terminals. Most NH fuses feature a trip indicator that visibly signals if the fuse element has blown. Additionally, each cover plate is equipped with a metal extraction lug, facilitating quick and easy removal from the holder using the recommended NH fuse puller tool.
