Schneider Electric EDB34020SA Mini Circuit Breaker

The Schneider Electric EDB34020SA is a three‑pole, 20 A E‑Frame mini circuit breaker designed for 480Y/277 VAC three‑phase service, built with bolt‑on mounting and a shunt‑trip option (TAA) for remote disconnection. It carries a 25 kA maximum interrupting capacity and is identified in Schneider Electric’s Square D line as part of the EDB family, specifically the EDB34020SA designation. This model provides reliable overload and short‑circuit protection for three‑phase feeders in industrial or commercial electrical distributions that operate at 480Y/277 VAC, combining a rugged molded‑case design with a compact form factor for easy panel integration. Its 3‑pole configuration and 20 A per‑pole rating make it a precise choice for safeguarding multi‑phase circuits, while the shunt‑trip option offers enhanced control in remote‑tripping scenarios.
