Square D by Schneider Electric FY14020A is a gray, 1-pole molded‑case circuit breaker designed for I‑Line panelboards. It is rated for 277 VAC on Phase A and provides 20 amps of thermal‑magnetic overcurrent protection for a single‑phase feeder or branch circuit in commercial electrical distributions. The FY14020A uses I‑Line mounting for quick, plug‑in installation in compatible Square D I‑Line panels, enabling straightforward replacement in A‑phase positions and ensuring protection for 277‑V circuits such as lighting runs and control circuits. As part of the FY family, this compact 1P MCCB balances a small footprint with robust protection suitable for panelboard configurations that specify FY series I‑Line breakers.
