Schneider Electric H221NRB Safety Switch Disconnect

Schneider Electric's H221NRB is a Square D heavy‑duty fusible safety switch disconnect rated for 30 A at 240 V, configured as a 2‑pole, 3‑wire device with a neutral for 1‑phase motor or equipment disconnects. It resides in a 3R enclosure with bolt‑on hub provisions, offering flexible mounting and integration options for commercial and light industrial applications, and it is specified to handle up to 7.5 hp at 240 V. This model represents the legacy H221NRB in the Square D safety switch family, with newer VisPacT variants such as VH221NRB described as replacements that preserve the same electrical ratings while introducing updated packaging and features.
