Overview

The Mersen G211606 is a high-capacity NH3 Size 3 gG fuse-link designed for robust protection in industrial electrical systems. Operating at 500VAC and 250VDC, this fuse-link offers a rated current of 315A and features isolated gripping tags for enhanced safety during installation and maintenance. The double indicator system provides clear visual confirmation of fuse status, simplifying diagnostics and reducing downtime. With a body width of 52 mm, it is compatible with standard NH fuse bases. As part of the Mersen NH system, it is classified as a plug-in fuse system, comprising a fuse-base, fuse-link with blade contact, and a fuse-link replacement device. The gG type designation signifies full-range breaking capacity, meaning these fuse-links are capable of interrupting any current surge from the lowest fusing current up to their rated breaking capacity. This allows them to be used as standalone protection for cables and equipment, safeguarding against both minor overloads and severe short-circuit events. They effectively protect electrical devices and industrial setups from the electrodynamic effects of very high short-circuit currents, preventing catastrophic damage. It is crucial to note that due to the design of the NH system, which cannot guarantee non-interchangeability of rated current, handling and replacement must be performed by a qualified professional. The Mersen G211606 is manufactured in France (FR) and adheres to stringent IEC standards, ensuring reliable performance and safety. Key specifications include a power dissipation of 25W at its rated current, a package weight of 0.65 kg, and a width of 51 mm. This fuse-link is an essential component for ensuring the integrity and operational continuity of critical industrial power distribution networks.
