Schneider Electric LV480903 FuPacT ISFL630 3 x 1P 630 A 120 kA Busbar-Mount Fuse Switch Disconnector

The Schneider Electric LV480903 FuPacT ISFL630 is a 3 x 1-pole vertical fuse switch disconnector rated 630 A at 690 V AC, built for direct mounting on 185 mm busbars. It takes NH3 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 ISFL630 is the 630 A vertical module in the FuPacT ISFL range, built around NH3 fuse carriers on the same 185 mm busbar centres and 100 mm width as the 400 A ISFL400; pick it when the circuit load exceeds 400 A continuous. 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. Its 25 kA/1 s short-time withstand and 52.5 kA making/breaking capacity at 690 V are higher than the 400 A variant's, which matters when selecting for selective coordination with downstream fused outgoing circuits, and the 3-padlock provision on the fuse-carrier handle supports lockout without extra hardware.
