Schneider Electric H221DS Fusible Disconnect Switch

The Schneider Electric H221DS is a heavy‑duty fusible disconnect switch rated for 30 A in a two‑pole, two‑wire configuration for 240 VAC circuits (1 phase), providing a robust safety stop for motor loads and other equipment. Housed in a 304 stainless steel enclosure, it delivers NEMA 4/4X/5 protection, making it suitable for outdoor, rain‑tight, and corrosive environments while retaining compact indoor versatility. The unit accommodates 240 VAC operation (up to 250 V DC) and is rated for up to 7.5 hp at 240 VAC, enabling effective protection and disconnection for moderate motor or heavy mechanical loads. Fuse provisions are designed to accept Square D Class H fuse inserts (with compatibility for related fuse classes), consolidating fuse protection within the same enclosure. As part of Square D’s heavy‑duty fusible safety switch family, the H221DS provides a code‑compliant isolation point that combines mechanical disengagement with fuse‑based protection, a common choice in industrial and commercial applications where rugged corrosion resistance and reliable single‑point disconnect are essential.
