Square D EGB14030 N Circuit Breaker 30A 277V 1P

Square D by Schneider Electric EGB14030 N is a bolt‑on, molded‑case circuit breaker from the EGB series configured for 1‑pole operation at 277 VAC. It is rated to 30 A and designed for use in Square D NF panelboards, providing local overcurrent protection for branch circuits in low‑voltage distribution systems. The device uses thermal‑magnetic trip technology to open on overload or short‑circuit conditions, with a 14–6 AWG Al/Cu conductor range and bolt‑on mounting for straightforward field installation. Key electrical ratings include 277 V AC operating voltage and a 35 kA short‑circuit interrupt rating at 277 V, supporting reliable protection for typical lighting and general electrical loads within its 30‑amp, single‑pole envelope. As part of the E‑Frame family, the EGB14030 combines compact form with robust protection tailored for panelboard applications, and it is commonly stocked by distributors and manufacturers under the exact model designation EGB14030 1P 30A 277V. This specific 1‑pole, 30‑amp model suits circuits where 277‑volt lighting or other 277‑V loads require reliable, code‑compliant overcurrent protection in a bolt‑on, NF‑panelboard installation.
