Square D H221N Safety Switch Fusible Disconnect

Square D by Schneider Electric H221N is a heavy‑duty fusible safety switch (fused disconnect) rated for 30 A at 240 VAC, with a 250 V DC rating for certain circuits. This indoor, two‑pole, three‑wire device includes one neutral and is designed for fusible operation with H‑type fuses, providing a dedicated disconnect point for power to downstream loads such as motors, compressors, or pumps in residential and light‑commercial installations. The switch is configured for 240 VAC systems and delivers up to 7.5 hp at 240 VAC, offering robust fault isolation while remaining compact enough for standard electrical panels. With an indoor‑rated NEMA 1 enclosure, the H221N is intended for environments where protection from dust and incidental contact is desired, and it coordinates with common Square D safety‑switch components to simplify installation and maintenance. This fusible disconnect provides a straightforward, reliable means to interrupt current for servicing or protection against overloads on 240 V circuits in homes, workshops, garages, and other small‑to‑medium installations.
