Overview

The Mersen V236044 is a high-quality NH Standard fuse-link, specifically a gG type, designed for robust protection in industrial electrical systems. Rated for 500VAC and 250VDC, this fuse-link operates at a nominal current of 125A and features a breaking capacity suitable for protecting cables and equipment from overcurrents and short circuits. Its NH1 size and 30mm body width ensure compatibility with standard NH fuse bases. The double indicator provides a clear visual confirmation of fuse status, enhancing safety and maintenance efficiency. As part of the NH plug-in fuse system, it comprises a fuse-link with blade contacts. The gG classification signifies a full-range breaking capacity, meaning it can interrupt any current surge from the lowest fusing current up to its rated breaking capacity, making it a versatile protective device. This fuse-link is crucial for safeguarding electrical devices and industrial setups against the severe electrodynamic effects of very high short-circuit currents. Key specifications include a rated voltage of 500V AC (IEC) and 250V DC (IEC), a rated current (In) of 125A, a power dissipation of 11.8W at In, and a body width of 29.5 mm. The package contains 3 units, with each fuse-link weighing approximately 0.28 kg. It is important to note that due to the design of the NH system, which cannot guarantee non-interchangeability of rated current, fuse-links of this type must be handled by qualified professionals. The Mersen NH1GG50V125 fuse-link is manufactured in France (FR) and adheres to IEC standards, ensuring reliable performance and safety in demanding electrical applications.
