Knife fuse link NH00 double indicator non-insulated holder aM 50A 690VAC LNH00050M6A

Safety and protection of electrical installations

NH00 blade fuse link is a reliable element protecting electrical circuits against overloads and short circuits. Designed for use in installations with a voltage of up to 690V AC, it provides effective protection for equipment and cables. Its construction with a double operating indicator facilitates quick identification of a blown fuse, minimizing downtime of the installation.

Characteristics and application

NH00 fuse link with aM characteristic (motor protection) is ideal for protecting circuits powering electric motors. The C characteristic allows it to react more slowly to short current surges, making it well-suited for withstanding the starting of motor-driven devices. The rated current of 50A makes this fuse link suitable for installations with medium loads. The NH00 construction, combined with a combined (double) indicator, ensures both visual status control and a quick response in the event of a failure.

Construction and mounting

The fuse link is manufactured in accordance with IEC 60269 standard, guaranteeing its high quality and reliability. It has an uninsulated handle, requiring special caution during installation and replacement. Mounting is done in dedicated NH00 fuse holders, providing a stable connection and safe operation. Power loss at rated current is 2.7W, minimizing energy losses in the installation. It is worth noting the lack of metal insulated grips (IMGL), which affects the method of mounting and compatibility with fuse holders.
