Mersen 125A German Standard Fuse NH00 690V ac, 77 mm NH00

Mersen NH00 German Standard Fuse 125A 690V ac is an industrial-grade, ultra-fast acting DIN80 size 00 fuse designed to provide reliable protection for electrical equipment in demanding environments.

This fuse features a rated current of 125 amperes and supports voltages up to 690 volts alternating current, making it suitable for heavy-duty industrial and commercial applications.

Manufactured with a lightweight resin body, it offers low inductance and very low I²t (pre-arcing and total) values, allowing for quick disconnection during faults and minimizing damage to connected electrical systems.

The fuse complies with international safety and quality standards including UL, EAC, CE, and CSA, ensuring high reliability and performance in global markets. It has an excellent breaking capacity of 200kA at 690Vac and 100kA at 600Vdc, enabling it to safely interrupt high fault currents.

Installation is facilitated by fixing centres spaced at 77 mm and a tag width of 26.5 mm, suitable for standard fuse holders. The compact physical size (length 54 mm, overall length 100 mm, height 65 mm, width 30 mm) allows integration in various electrical distribution assemblies.

The fuse also includes a visual status indicator to quickly identify blown fuses during maintenance and diagnostics.

These fuses are widely used in industrial, manufacturing, electrical distribution, HVAC, and automation systems for protecting motors, transformers, and other critical electrical infrastructure.
