Square D D-221-N 30 Amp 240V Fusible Safety Switch

This industrial heavy-duty safety switch disconnect box manufactured by the Square D Company. It features the classic metal construction with embossed "ON" and "OFF" lettering along the sides and a robust external side-operating handle lever with a black grip. The original metallic data faceplate is intact on the cover lid, detailing the specifications: Catalog No. D-221-N, 30 Amp, and 240 V.A.C. rating. The grey painted finish shows an authentic, aged industrial patina with minor surface scratches, light grease markings, and localized oxidation/rust spots near the edges, giving it fantastic vintage character for collectors or functional repurposing.
