Schneider Electric NSB EDB14020 Miniature Circuit Breaker

The Schneider Electric EDB14020 E‑Frame miniature circuit breaker is a 20 A, 1‑pole device designed for 277 VAC circuits and bolt‑on installation in Square D NF panelboards. It carries up to 25 kA maximum interrupting capacity and is labeled as TAA compliant for U.S. procurement. As part of Schneider Electric's E‑Frame family, the EDB14020 is intended to protect branch circuits within NF panelboards that accept E‑Frame breakers, offering a compact, bolted mounting option for reliable, space‑efficient protection. Typical applications include lighting and general purpose circuits in commercial or light industrial distribution where 277 V is used and a single‑pole protector is appropriate.
