Why Choose the Mersen NH000GG69V4 NH Fuse-Link?
The Mersen NH000GG69V4 is a compact, high-performance DIN NH gG fuse-link designed to provide dependable protection against overloads and short circuits in low-voltage electrical distribution systems. Part of Mersen's established NH gG 690 V AC fuse-link range, it is suitable for industrial switchgear, control panels, distribution boards and machinery requiring reliable general-purpose circuit protection.
This fuse-link combines a 4 A rated current with voltage ratings of up to 690 V AC and 250 V DC. Its gG operating characteristic provides full-range protection for cables, conductors and electrical equipment, allowing the fuse to respond effectively to both sustained overload conditions and high-level short-circuit faults.
The NH000GG69V4 features a compact NH000 body size, robust ceramic construction, silver-plated copper blade contacts and live gripping lugs. A double indication system provides clear identification when the fuse has operated, helping maintenance engineers locate faults and replace affected fuse-links efficiently.
