Introducing the Square D FA320401021 — a 40 A, 3-pole, 240 V circuit breaker designed to deliver reliable protection for panelboards, load centers, and broader electrical distribution systems. This model is especially practical for retrofit work and maintenance planning when keeping the same part number across inventories and service records is important.
- Three-pole design provides simultaneous interruption of all hot legs in 3-phase systems, improving safety and simplifying service.
- 40 A rating protects medium-load circuits and feeders within commercial or light industrial environments.
- 240 V operation aligns with common three-phase equipment and standard power distribution configurations.
- Consistent part numbering supports streamlined retrofits and maintenance planning, reducing part-number confusion over time.
- Panel and distribution readiness is designed for compatibility with Square D panelboards and load centers that accept this type of 3P, 240 V breaker.
The FA320401021 is more than a replacement part—it’s a strategic choice for professionals who value compatibility, traceable component IDs, and predictable maintenance workflows across a facility’s electrical footprint. When reliability and scheduling matter, this Square D breaker helps you stay on track without hunting for alternate parts.
