The gG curve provides full-range overcurrent protection — it clears both overloads and short-circuits — making it a standard choice for motor feeder and distribution circuits where coordination with downstream devices is needed. Each unit includes a striker for local blown-fuse indication, and the part ships as a set of 10 fuses. The striker mechanism is useful in fused-disconnector applications where a visual flag confirms the fuse has operated, saving time during fault-finding on a panel. The 14 x 51 mm form factor fits standard NFC fuse holders and fuse-disconnector bases in the TeSys GS range. The gG curve and 4 A rating suit it for protecting control transformers, small motor circuits, or distribution sub-feeds where the full-range characteristic avoids nuisance blowing on inrush. The striker flag is visible through the fuse holder window on most TeSys GS switch-disconnectors, so a quick visual scan of the panel confirms fuse status without opening the door.","metaTitle":"Schneider Electric DF3EN04 TeSys GS Cartridge Fuse, 4A 500V","metaDescription":"Schneider Electric DF3EN04 NFC cartridge fuse, 14x51mm, gG curve, 4A 500V AC, striker, set of 10.
