This 3 A, Trip Curve C unit is part of the Bulletin 1492-SPM family and is intended to guard control circuits and auxiliary loads in industrial automation panels without interrupting larger feeders. It is specified for 277 V AC operation (1P, no neutral) and carries a 48 V DC rating for compatible low-voltage circuits, making it suitable for mixed AC\/DC control applications. The 1492-SPM1C030 delivers fast response to short circuits while minimizing nuisance tripping during normal inrush, helping protect relays, timers, contactors, and other control equipment in space-constrained panels. In accordance with UL 1077, it offers a robust interrupting capability appropriate for common 1P protective needs, with an interruption rating that supports reliable fault interruption for currents in the 0.5–32 A range. The device’s straightforward, plug-in 1-pole form factor and no-neutral requirement for 1P configurations simplify integration into existing control architectures, delivering dependable supplementary protection where every amp matters. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46243657580778,"sku":null,"price":58.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-078.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1492-spm1c030-supplementary-protector","provider":"GTG Hardware","version":"1.0","type":"link"}
