Why Choose the Mersen NH0GG69V40P-2 NH Fuse Link?
The Mersen NH0GG69V40P-2 is a premium NH0 gG low-voltage HRC fuse link with striker, engineered to provide reliable full-range protection against overloads and short circuits in industrial and commercial electrical installations. Manufactured by Mersen, this DIN-standard fuse link is designed for demanding power distribution systems operating at up to 690 V AC.
This NH0 fuse link incorporates an integrated mechanical striker, enabling remote signalling or automatic tripping when used with compatible auxiliary switches or fuse switch-disconnectors. Its ceramic body, blade-contact construction and live gripping tags provide dependable performance in industrial environments where fast fault indication is essential.
With a rated current of 40 A, a 690 V AC voltage rating and an 80 kA AC breaking capacity, the NH0GG69V40P-2 is ideal for protecting feeders, switchboards, control panels, machinery and industrial distribution equipment. Its gG utilisation category provides full-range protection from sustained overloads through to severe short-circuit faults.

Reliable Full-Range Electrical Protection
The Mersen NH0GG69V40P-2 provides dependable protection against overload and short-circuit currents by rapidly interrupting fault currents before damage can occur to cables, switchgear and connected electrical equipment. Its HRC construction limits thermal and electrodynamic stresses, helping improve equipment reliability and minimise downtime.
The integrated striker is mechanically released when the fuse operates and can actuate compatible auxiliary contacts, alarms or switch-disconnector mechanisms. This enables faster fault detection and coordinated isolation of affected circuits within industrial power distribution systems.
Typical Applications
- Industrial switchboards.
- Power distribution systems.
- Control panels.
- Cable and feeder protection.
- Industrial machinery.
- Fuse switch-disconnectors and electrical switchgear.
