Schneider Electric LV480902 FuPacT ISFL400 3 x 1P 400 A 120 kA Busbar-Mount Fuse Switch Disconnector

The Schneider Electric LV480902 FuPacT ISFL400 is a 3 x 1-pole vertical fuse switch disconnector rated 400 A at 690 V AC, built for direct mounting on 185 mm busbars. It takes NH2 fuses, delivers a 120 kA breaking capacity, and needs no extra clearance for current-transformer installation, since its compact 100 mm width keeps the panel footprint small for distribution and equipment-protection duty.

Selection Notes

The ISFL400 is the 400 A vertical module in the FuPacT ISFL range, built around NH2 fuse carriers and direct connection to 185 mm busbars; projects needing a higher current or NH3 fuses on the same busbar centres use the 630 A ISFL630 instead. Three individually switchable 1-pole units stack one above the other to form a 3-pole assembly, so each phase keeps visible-break isolation per EN/IEC 60947-3 and its own contact-position indicator. The 15 kA/1 s short-time withstand and 120 kA breaking capacity let it serve as a sub-distribution disconnector ahead of downstream fused outgoing circuits, while the 3-padlock provision on the fuse-carrier handle supports lockout without extra hardware.
