Schneider Electric EGB34030 3P Circuit Breaker

Schneider Electric's Square D EGB34030 is a 30A, three‑pole, E‑frame molded‑case circuit breaker designed for 480Y/277VAC distribution. This bolt‑on, TAA‑compliant device provides thermal‑magnetic overcurrent protection for three‑phase circuits and carries an interrupting rating of up to 65 kA at 480Y/277 VAC, making it suitable for feeders and branch circuits in commercial and light industrial panelboards. As part of the Square D EGB family, it is intended for use in NF panelboards and is compatible with other E‑frame breakers in the same lineup. Typical applications include protection of 3‑phase loads in 480Y/277V systems—such as HVAC equipment, control panels, and distributed power feeds—where reliable fault interruption at high line voltage is required.
