The Schneider Electric DF2GGN1051 is a DIN NH0 blade fuse with a gG characteristic, rated 50 A at 500 V AC. The gG curve means it provides full-range protection — both overload and short-circuit — for general-purpose applications like cable protection, distribution boards, and motor feeder circuits. The NH0 form factor fits standard NH fuse bases and switch-disconnectors common across European panel builds.
The 500 V AC rating covers 400 V three-phase systems common in industrial distribution, with headroom for voltage transients. The NH0 size is the physical envelope: 50 A is near the top of the NH0 range, so the fuse element is sized for that current density and the blade contacts match the NH0 base's clip spacing.
