Why Choose the Mersen NH00GG69V40 NH Fuse Link?

The Mersen NH00GG69V40 is a reliable NH00 size gG fuse link designed to provide full-range protection for low-voltage electrical cables, switchgear and industrial power distribution systems. Rated at 40 A and 690 V AC, this high rupturing capacity fuse protects against both overloads and short-circuit faults in commercial and industrial installations.

Its gG operating characteristic provides complete protection across its entire operating range, making it ideal for safeguarding electrical distribution circuits, control panels and industrial equipment. The fuse rapidly interrupts fault currents while also protecting against prolonged overload conditions.

The NH00GG69V40 features a robust ceramic body, silver-plated blade contacts, live gripping tags and an integrated double indicator that clearly identifies when the fuse has operated. Designed to DIN NH standards, it is intended for installation in compatible NH00 fuse bases and switch-fuse disconnectors.
