Square D FGA34090 – 90A 3 Pole Molded Case Circuit Breaker In Demand

Built for heavy-duty commercial environments, this 90A F-frame circuit breaker provides essential long-time and instantaneous trip functions. The device mounts into legacy Square D I-Line panelboards and switchboards. Because it only requires 3 inches of mounting space, it acts as the preferred replacement over the newer HGA36090, which demands a wider 4.5-inch slot. Capable of interrupting 35kA at 480Y/277V, the breaker includes standard load lugs and is fully HACR rated for HVAC equipment.
