Square D EGB34030 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase industrial power distribution systems. It features a 30A current rating and a 480V AC voltage rating, housed within a compact E-Frame/G Frame construction measuring 143.76 mm H x 74.68 mm W x 102.87 mm D and weighing 3.801 lb. The breaker is certified to cULus and UL standards and operates across a temperature range of -25 to 70 °C, utilizing a thermal magnetic trip unit for long-time and instantaneous (LI) protection. Its typical application is within NF panelboards, where its 35kA interrupting rating at 480V, bolt-on lug connection, and compatibility with 6-12 AWG aluminum or 6-14 AWG copper wire ensure secure integration.
