Schneider Electric FGA34020 I-Line Circuit Breaker

Schneider Electric's Square D FGA34020 I-Line circuit breaker is a 3-pole, 20-amp molded‑case protector designed for 480Y/277V three‑phase systems with I‑Line plug‑on installation. This unit employs a thermal‑magnetic trip with a non‑interchangeable trip mechanism to deliver both long‑time and instantaneous protection. It carries UL/CSA/NOM listings with interrupting ratings of 65 kA at 240 VAC and 35 kA at 480Y/277 VAC, making it suitable for distribution panels where higher fault currents may be encountered. As part of the FGA family, it is intended for use in Square D I‑Line panelboards and other compatible distribution environments that require a dedicated 3‑pole 20 A breaker for 480V class systems.
