Mersen W222498 - The NH system is classified among plug-in fuse systems and is composed of: • fuse-base (possibly including terminal covers and phase barriers) • fuse-link with blade contact • fuse-link replacement device (LV HRC fuse puller) Since the design of this system cannot guarantee non-interchangeability of rated current it must be handled by a qualified professional. Type gG NH fuse-links are full range breaking capacity fuse-links and are used to protect cables and equipment. They can interrupt any current surge, from the lowest fusing current up to their breaking capacity, and so can be used alone as protection. They also protect electrical devices and industrial set-ups from the electrodynamic effects of very high short-circuit currents. 500 Volts 80 Amps gG NH00 with puller lugs series.

Overview

The Mersen NH00 80A 500V gG NH fuse-link with puller lugs (SKU: W222498) is a full-range breaking capacity fuse-link designed for industrial electrical protection. Part of the NH plug-in fuse system, this fuse-link provides reliable protection for cables and equipment by interrupting current surges from the lowest fusing current up to its breaking capacity of 80 kA. It safeguards electrical devices and industrial setups from the electrodynamic effects of high short-circuit currents, ensuring operational safety and continuity. This gG-rated fuse-link is classified under IEC 60269-1 and meets NF EN 60269-1, VDE 0636-10, and DIN 43620 standards, making it suitable for demanding industrial applications. The NH00 series features puller lugs for easy installation and replacement, reducing downtime during maintenance. The fuse-link is non-interchangeable by design, requiring handling by qualified professionals to ensure proper current rating selection. With a voltage rating of 500V AC and a current rating of 80A, this fuse-link is ideal for protecting critical electrical infrastructure in manufacturing, power distribution, and industrial automation systems. Its compact size (NH00) and blade contact design ensure compatibility with NH fuse bases, including those with terminal covers and phase barriers for enhanced safety. The fuse-link’s power dissipation is optimized at 4.6W, balancing thermal performance and protection efficiency. Mersen, a leader in electrical protection solutions, manufactures this fuse-link in the US, ensuring high-quality construction and adherence to international standards. The NH system’s modular design allows for seamless integration into existing electrical panels, while the puller lugs simplify fuse replacement without tools. This makes the W222498 an essential component for maintaining electrical safety and reliability in industrial environments.
