Why Choose the Mersen NH00GG50V40 NH Fuse-Link?

The Mersen NH00GG50V40 is a reliable DIN NH gG fuse-link designed to protect cables, conductors and low-voltage electrical equipment against overloads and short-circuit faults. Part of Mersen's established NH gG 500 V AC fuse-link range, it is suitable for industrial switchgear, distribution boards, control panels and machinery installations.

Featuring a 40 A rated current and a 500 V AC voltage rating, the NH00GG50V40 uses a gG full-range operating characteristic. This enables the fuse-link to respond to sustained overload currents as well as severe short-circuit faults, providing comprehensive protection for general-purpose electrical distribution circuits.

The fuse-link is manufactured in the compact NH00 size and incorporates a robust ceramic body, DIN NH blade contacts and a double indication system. Its gripping-lug design supports safe removal and replacement using an appropriate NH fuse-link replacement device.
