It is rated for 4 A and supports 277\/480 VAC service, with a Type K (K-curve) magnetic trip intended for fast response to short circuits and to handle motor inrush conditions common in commercial and light-industrial installations. The device is designed for plug-in DIN-rail installation and offers compact protection for branch circuits in control panels, panel boards, and other enclosures that follow standard ABB S272 form factors. Across multiple distributors and ABB-related listings, the S272-K4A appears as a 2P, 4 A, 277\/480 V MCCB with K-curve characteristics, reinforcing its role as a widely used, DIN-rail protection device in modern electrical installations. Because it is part of ABB's legacy S272 lineup, it integrates with ABB accessories and offers a compact footprint suitable for dense panel layouts.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46257235984618,"sku":null,"price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-085.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/abb-s272-k4a-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
