Product Description
Mersen NH00 NH Fuse model Q320151 is a robust electrical fuse rated at 50 amperes and 690 volts AC designed to protect power semiconductor equipment by interrupting fault currents efficiently. This fuse belongs to the NH fuse family, specifically the NH00 size, and is built for high rupture capacity (HRC) to quickly break excessive current, protecting sensitive industrial and electrical installations.
The fuse features a Protistor® body compliant with DIN 43620 standards, ensuring consistent high quality and reliable long-term operation.
With a fuse length of 50mm and overall length of 79mm, combined with a tag width of 6mm and a plain blade NH type tag, this fuse fits securely in NH fuse holders for ease of installation and maintenance. The dimensions of 47.5mm height and 29.5mm width offer a compact form factor suitable for various electrical panels.
Designed for application category aR, the NH fuse protects semiconductor devices with a fast fuse speed (FF), capable of handling high breaking capacities essential in heavy-duty industrial environments. The included fusion striker on the body enables activation of micro-switches (sold separately) to signal fuse operation for automation and monitoring systems.
Certified to IEC standards and manufactured in Tunisia, this fuse is a trusted choice for industrial, electrical, and manufacturing power protection uses requiring reliable and safe circuit interruption at high current levels.
