Knife fuse link NH00 double indicator non-insulated aM 100A 690VAC LNH00100M6A

Hager fuse links – safety for installations and equipment

This NH00 fuse link model is a reliable element protecting electrical circuits against overloads and short circuits. Designed for use in AC installations with a voltage of up to 690V, it provides effective protection for both installations and connected devices. A dual operation indicator facilitates quick identification of a blown fuse, significantly reducing repair time and minimizing downtime.

This fuse link is designed to protect motors – its aM (formerly gG) characteristic allows for short-term current loads, typical for motor starting, without unnecessary tripping. This is crucial in industrial and workshop applications where motors are commonly used. The construction with an uninsulated grip requires special caution during installation and replacement, but ensures a firm grip and ease of manipulation.

Construction features and application

The NH00 fuse link is a standard solution in low-voltage switchgear systems. Its construction allows for mounting in dedicated fuse holders, ensuring a safe and stable connection. A rated current of 100A makes it an ideal choice for protecting circuits with medium loads. A power loss of 5.5W at the rated current minimizes energy losses in the installation.

The use of a combined (dual) indicator is a practical solution – visual information about a blown fuse eliminates the need for disassembly to check its status. This saves time and increases the efficiency of work for both the installer and the end user. Additionally, the lack of metal insulated clips (IMGL) simplifies installation and replacement in standard fuse holders.

Advantages for professionals and users
