Schneider Electric EGB14030U Molded Case Circuit Breaker

Schneider Electric's Square D EGB14030U molded‑case circuit breaker is a 1‑pole, 30 A, 277 V AC device from the EGB family, designed for bolt‑on mounting in Square D NF panelboards. This thermal‑magnetic MCCB provides overcurrent protection for lighting and general distribution circuits in commercial environments requiring compact, reliable protection in distribution panels. The EGB14030U features an E‑Frame construction that facilitates replacement in compatible panels and is rated for operation in ambient environments around 40°C. The unit is intended for single‑pole, 277 VAC circuits and is commonly used to protect lighting feeders and other branch circuits in NF panelboard installations. As part of Schneider Electric's legacy line of miniature molded‑case breakers, the EGB series emphasizes robust protection with straightforward mounting in Square D panels, making it a suitable choice for 277‑V, 30‑amp branch circuits in commercial distribution systems.
