Schneider Electric EGB14030 SWD Circuit Breaker

Schneider Electric's Square D EGB14030 is a 30 A, 1-pole molded‑case breaker from the EGB (E‑Frame) family, designed for 277 VAC service and bolt‑on mounting in NF panelboards. This thermal‑magnetic device provides protection for single‑phase lighting or small‑power branch circuits and carries a high interrupt rating suitable for commercial distribution panels (up to 65 kA, per manufacturer data). In Schneider Electric literature, the 30 A version is listed for HID (high‑intensity discharge) loads, while 15 A and 20 A versions are SWD (switching duty) rated, so verify the exact designation for your installation. The EGB14030 is intended to fit legacy Square D NF panelboards and other E‑Frame interiors, offering a compact, straightforward protection option when a 277 VAC, 1P, 30 A breaker is required.
