NH1 is a common designation for fuses that comply with the European DIN Standard, particularly in Germany. The NH (Neozed Hochsicherung) system is widely used for protecting low-voltage electrical systems, including batteries. The number “1” indicates the specific size or range of the fuse.
A 250A NH1 fuse is intended to handle a maximum current of 250 amperes. Its purpose is to protect the battery and electrical circuits connected to it from excessive current flow, which could lead to damage or safety hazards.
