Why Choose the Mersen NH2GG69V50 NH Fuse-Link?
The Mersen NH2GG69V50 is a high-performance NH2 gG fuse-link designed to provide full-range protection for cables, switchgear and electrical equipment in low-voltage power distribution systems. Manufactured to the DIN NH format, it protects circuits against both sustained overload currents and high-level short-circuit faults.
Rated at 50 A, 690 V AC and 250 V DC, the NH2GG69V50 is suitable for industrial, commercial and infrastructure applications requiring dependable circuit protection at elevated operating voltages. Its gG operating characteristic provides protection across the complete current range, allowing it to act as the primary protective device for general distribution circuits.
The fuse-link incorporates live gripping tags, a double visual indicator and a durable ceramic body. Its standard NH2 blade-contact design supports installation in compatible NH fuse bases and fuse-switch disconnectors, while its current-limiting performance helps reduce the thermal and mechanical effects of electrical faults.
