The PQ4203G variant is rated for up to 240 V AC, with common configurations supporting 120\/208\/240 V, and houses three fuses plus an integral ground bus within an FS-frame, NEMA 1 enclosure for indoor installations. As a plug-in bus plug, it mates with compatible I-Line busway sections to feed downstream equipment such as panels or switches, delivering localized protection and straightforward fuse replacement in commercial or light industrial environments. The four-conductor arrangement supports three current paths plus a ground, aligning with a 30 A rating for compact feeders and preserving the busway’s modular, plug-in design. Typical applications include providing a fusible feed to branch circuits in power distribution layouts where a fusible protection device is preferred at the point of use along an I-Line bus run.\u003c\/p\u003e\u003c\/div\u003e","brand":"SQUARE","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46258978390250,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-012.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/square-d-pq4203-fusible-bus-plug-horizontal-unit","provider":"GTG Hardware","version":"1.0","type":"link"}
