Schneider Electric 175GXMSJD80E Current-Limiting Power Fuse

Schneider Electric’s Square D 175GXMSJD80E is a DIN‑mounted, current‑limiting power fuse rated for 17.5 kV and 80 A, engineered to protect medium‑voltage switchgear and feeders by quickly limiting fault current. As an E‑rated, high‑voltage fuse, it supports fast interruption with a design‑voltage rating of 17.5 kV and an interrupt rating up to 65 kA, making it suitable for protecting MV distribution gear and fusible switch assemblies in applicable Square D/Bussmann configurations. The model is cataloged across distributors as 175GXMSJ80E or SQD 175GXMSJD80E, reflecting its place in the 17.5 kV, 80 A family of current‑limiting fuses. Typical applications include protection of medium‑voltage feeders, transformers, and bus sections in switchgear installations where DIN form‑factor fuses are used.
