Schneider Electric EGB34070SA Mini Circuit Breaker

Schneider Electric’s Square D EGB34070SA is a three‑pole, molded‑case circuit breaker in the E‑Frame family, rated for 70 A and designed for bolt‑on mounting in industrial panelboards. It tolerates 480Y/277 VAC service and provides shunt‑trip capability with a 120 V coil, enabling remote disconnection for safety interlocks and protective sequencing. Distributor listings show an interrupting rating up to 65 kA at 480 V for this model, reflecting its suitability for high‑fault‑current installations, while the device uses thermal‑magnetic protection and is bolt‑on for stable, serviceable installation. As part of Square D’s E‑Frame lineup, it is commonly applied in lighting panels, motor control centers, and other three‑phase feeder applications where a dedicated remote trip is required. The EGB34070SA designation identifies a 3P, 70A, 480Y/277 VAC, bolt‑on MCCB with shunt‑trip options, aligning with standard Square D specifications for industrial electrical protection.
