Schneider Electric FY14020B I-Line Circuit Breaker

Schneider Electric's Square D FY14020B is a 20 A, 277 VAC, single-pole molded‑case circuit breaker designed for I-Line plug‑in panel installations. The device uses a thermal‑magnetic trip to provide overload and short‑circuit protection and is intended for use in I-Line panelboards that accept FY series breakers. As part of the Type FY family, the FY14020B features I-Line mounting that lets it snap into compatible Square D/I-Line bus systems for straightforward installation and secure operation. With its 1P configuration, it protects a single hot conductor in standard electrical distribution applications, such as lighting and general branch circuits in commercial and industrial environments where 277 VAC is the system voltage. This breaker is manufactured by Square D, a brand of Schneider Electric, and is designed to fit the appropriate I-Line distribution equipment designed to accommodate FY-series breakers.
