Schneider Electric SE 9999-SF1 Fuse Block Kit

Schneider Electric's Square D 9999-SF1 Fuse Block Kit is a Class 9999, Type S fuse block assembly intended for Size 0/1 configurations. This kit (part number 9999-SF1) is described as a Fuse Block Kit with Clips Not Included, and it weighs 1.27 lb, making it a compact, field-installable component for protection schemes in control panels. Classified as a Panel Accessories item and a Fuse Holder, the SF1 provides the structural and electrical interface to hold fuses within compatible Square D equipment. Designed to integrate with other 9999 accessories in applications that require a fusible-disconnect configuration, this kit helps installers assemble a reliable protection path while preserving access to the fuse base area. Note that clips are not included with this kit, so maintainers should source the appropriate fuse clips separately to complete the assembly. Designed to be used with other 9999 Type S accessories to configure a complete fuse-based protection module, the SF1 aligns with Square D's tradition of modular, field-installable control components for space-constrained industrial panels.
