Why Choose the Mersen NH22GG50V160-1 160A 500V NH2 gG Fuse Link?
The Mersen NH22GG50V160-1, manufacturer reference Y215692C, is a 160 A NH size 2 gG fuse link designed for full-range protection of cables, conductors and electrical equipment in low-voltage distribution systems. Its gG operating class provides protection against both overload and short-circuit currents when correctly selected and coordinated for the installation.
Rated at 500 V AC, the NH22GG50V160-1 uses the standard NH size 2 format and is intended for installation in compatible NH fuse bases and fuse switch disconnectors. This special-series version features insulated metal gripping lugs and a combination indicator for practical use in industrial electrical distribution equipment.
The NH22GG50V160-1 provides a rated breaking capacity of 120 kA AC, enabling it to interrupt substantial prospective fault currents under its specified operating conditions. Power dissipation at rated current is 13.5 W, while the manufacturer catalogue lists a weight of approximately 597.4 g per fuse link.
