Schneider Electric EDB34125SA N Circuit Breaker

Schneider Electric's EDB34125SA is a 125 A, three-pole molded‑case circuit breaker designed for 480Y/277 VAC three‑phase power distribution, delivering up to 25 kA of interrupting capacity and featuring bolt‑on mounting for secure panel installation. As part of the E‑Frame family, it uses a thermal‑magnetic trip mechanism to provide reliable overload protection and fast short‑circuit clearing for feeders and branch circuits in commercial and light industrial power systems. The unit includes a 120 V shunt‑trip option for remote tripping and is listed under the Trade Agreements Act (TAA), meeting government procurement requirements where applicable. With its 480Y/277 VAC rating, 125 A rating, and three‑pole configuration, this breaker is well suited for protecting feeders in distribution panels and other electrical distribution equipment in commercial buildings and light industrial facilities that require robust, code‑compliant protection for critical loads. Bolt‑on mounting supports a rigid installation in compatible enclosures, and the EDB34125SA’s specification aligns with utility and contractor expectations for long‑term reliability in demanding environments.
