Socomec DSF125-690 Combination Switch Fuseblock

The Socomec DSF125-690 Combination Switch Fuseblock is a manually operated three-pole fuse-switch block (FUSERBLOC) rated for 125 A and 690 VAC. Designed to accept 22 × 58 NFC fuses, this DSF125-690 combines switching and overcurrent protection in a compact frame—frame size 3—for streamlined panel integration. It features a direct front handle and external front and left-side operator, enabling front-access operation in enclosed switchgear. The device supports an I-0-Test sequence for position verification and is intended for use in three-phase electrical installations where reliable isolation and protection are required in a single enclosure. As a product from Socomec, it sits within the FUSERBLOC family, offering a rugged solution for industrial control panel builders and distribution boards that demand a dedicated disconnect and fuse assembly in a single unit. The DSF125-690's 690 VAC rating and 125 A current rating enable it to handle typical motor control and line-disconnect roles in commercial and industrial environments.
