Schneider Electric EGB34030 Bolt On 3 Pole Circuit Breaker

Schneider Electric's Square D EGB34030 bolt-on 3-pole miniature circuit breaker provides robust 3‑phase overcurrent protection for 480Y/277V systems, rated at 30A with a maximum interrupting capacity of 65 kA. As an E‑Frame, bolt‑on device, it installs in compatible enclosures and is designed for reliability in commercial and light‑industrial panelboards, protecting feeders to motors, HVAC equipment, and other three‑phase loads from short circuits and overloads. This 30A, 3P breaker is listed as TAA compliant and intended for use in Square D panel configurations that require bolt‑on protection of 480V circuits, with terminals that accommodate common conductors such as 14‑2/0 AWG aluminum or copper. The EGB34030 is part of Schneider Electric’s legacy E‑Frame family, offering a compact footprint and straightforward field installation while delivering thermal‑magnetic protection and consistent performance across demanding distribution applications. Ideal for retrofit or new installations where a bolt-on 3‑pole solution is needed to feed industrial equipment and data center infrastructure, this breaker is designed to integrate with Schneider Electric’s broader Square D ecosystem for coordinated protection and reliability.
