Certified Square D FA340201021 – 20A 3 Pole Molded Case Circuit Breaker

Built for industrial environments, the Square D FA340201021 is a 3-pole thermal-magnetic molded case circuit breaker. It is engineered to mount into Square D I-Line panelboards, offering robust overcurrent protection with long-time and instantaneous (LI) trip functions. This legacy F-Frame unit is replaced by the PowerPact HDA36020 combined with an S29386 shunt trip accessory. It provides an 18 kAIC rating at 480VAC and includes a Visi-Trip indicator for clear status visibility.
