The Mersen NH000 model 80A NH Fuse is engineered to provide high reliability and safe circuit protection for electrical systems operating at 690V AC. This high rupture capacity fuse meets IEC and DIN standards, making it suitable for demanding industrial and commercial applications.
Its NH000 fuse size and NH000UD series classification position it as a precise component especially for protecting power semiconductors and related equipment. The fuse is classified under the aR application category, ensuring fast-acting protection with a fuse speed rating of FF, ideal for isolating faults quickly to prevent damage.
The fuse dimensions including a 79 mm overall length and 40.5 mm height allow for compact mounting within electrical panels. The 6 mm tag width ensures firm and secure connection with fuse holders or circuit breakers. High rupture capacity is a key feature that allows this fuse to safely interrupt fault currents, which protects downstream circuitry effectively.
This device is fitted with a fusion striker mechanism that can activate a micro-switch attached to the fuse body; however, the micro-switch is available separately (stock no. 448-3241). This feature provides enhanced monitoring and control capability in industrial or automation setups.
Manufactured in Tunisia, the product adheres to high quality standards ensuring durability and consistent performance in power distribution and control circuits. The fuse is rated 80 amperes for reliable current limiting.
It complies with IEC and DIN approvals ensuring international electrical safety norms. The NH000 size facilitates usage in standardized fuse bases and holders. Suitable for industrial and manufacturing environments requiring robust circuit protection.
The high rupture capacity supports protection of sensitive power semiconductors from excessive currents. Compatible with accessory micro-switches to provide trip indication features. Ideal for installation in electrical automation, power distribution panels, and industrial electrical infrastructure. Explore more Mersen Fuses and accessories on EnvMart.
