Overview
The LV480902 is a Schneider FuPacT ISFL400 fuse-switch disconnector rated for 400 A switching current with a 120 kA breaking capacity at 690 V, built for equipment protection, monitoring, and distribution in a 3-pole NH2 frame. It provides a visible break and is certified for isolation per EN/IEC 60947-3, with a Class II front face and IK07 impact rating.
Selection and sizing
The 400 A uninterrupted rating and 120 kA breaking capacity suit it for high-fault-current distribution panels where the upstream transformer or bus can deliver over 100 kA. The NH2 frame accepts DIN fuse links up to 400 A.
