Schneider Electric EDB34070U Three Phase Circuit Breaker

Schneider Electric's Square D EDB34070U is a three-pole molded‑case circuit breaker (MCCB) in the E‑Frame family, rated for 70 amperes in 480Y/277 VAC installations and designed for bolt‑on mounting in commercial or light industrial panels. As a Type EDB device, it provides thermal‑magnetic protection for three‑phase circuits and is suitable for feeders, motor circuits, and distribution panels that require overload and short‑circuit protection. When connected to a 480Y/277V system, the EDB34070U offers a short‑circuit interrupting capacity up to 25 kAIC, helping isolate faults quickly. The unit is specified for three‑phase operation with a 70 A rating, and its bolt‑on mounting facilitates field installation in compatible enclosures. This model is commonly used in commercial and industrial electrical distributions where 3P protection at the 70 A level is needed, and it aligns with the Square D EDB series offerings for higher‑voltage distribution networks.
