Square D FGA34020 – 20A 3 Pole Molded Case Circuit Breaker Crafted

Built to accommodate older switchgear, this legacy F-Frame MCCB utilizes Visi-Trip technology for rapid fault identification. Designed specifically for Square D I-Line panelboards requiring a narrow 3-inch mounting footprint. It provides 65kAIC protection at 240VAC and 35kAIC at 480Y/277VAC via fixed thermal-magnetic LI functions. Maintaining the original FGA form factor is crucial for older setups, as the modern HGA36020 replacement requires an expanded 4.5-inch space within the enclosure.
