The DF2GGA1051 is a Merlin Gerin NH0-size AM-type cartridge fuse rated at 50 A continuous at 690 V AC. The AM designation means it's a general-purpose motor-protection fuse — it handles the inrush of a motor start without nuisance blowing, but clears fast enough on a hard fault to protect downstream contactors and cables. NH0 is the compact blade size, common in European-style fuse-switch disconnectors and DIN-rail fuse bases.
