MERSEN FUSE 500V NH1 C/P gG 315A Z201847
Mersen NH1GG50V315P-2 is a 315 A 500 V AC NH size 1 gG striker-equipped fuse link with a 120 kA AC breaking capacity for full-range low-voltage circuit protection.
Why Choose the Mersen NH1GG50V315P-2 315A 500V NH1 gG Fuse Link?
The Mersen NH1GG50V315P-2, manufacturer reference Z201847, is a 315 A NH size 1 gG fuse link designed for full-range protection of cables, conductors and electrical equipment in low-voltage distribution systems. Its gG utilisation category provides protection against both overload and short-circuit currents when correctly selected and coordinated for the installation.
Rated at 500 V AC, the NH1GG50V315P-2 uses the standard NH size 1 format for installation in compatible NH fuse bases and fuse switch disconnectors. The fuse is equipped with a striker, enabling mechanical fuse-operation indication or actuation when used with compatible equipment.
The NH1GG50V315P-2 provides a rated breaking capacity of 120 kA AC, making it suitable for industrial distribution systems with substantial prospective fault currents. Power dissipation at rated current is 25 W, while the manufacturer-listed weight is approximately 0.35 kg per fuse link.
