Square D EGB14030SA is a one‑pole, 30 A molded‑case circuit breaker from the EGB family, rated for 277 V AC and designed for remote tripping via a 120 V shunt‑trip coil. This bolt‑on, thermal‑magnetic device provides up to 35 kA interrupting capacity at 480 V and is built for use in commercial panels where fast, remote shutdown is required. The SA suffix indicates the integrated shunt‑trip option, enabling actuation from a separate control circuit to meet safety interlock and emergency‑shutdown requirements.
