Square D | FA36030CBA | Circuit Breaker | 30A | 3-Pole | 600V

Square D FA36030CBA Circuit Breaker delivers precise 30A, three-pole protection for 600V electrical systems. Designed for maintenance, retrofit, and replacement projects, this breaker helps you keep multi-phase circuits safe while minimizing downtime and wiring disruption.

What makes this breaker stand out is its synchronized three-pole design, which ensures all three phases interrupt together. That coordinated trip reduces the risk of phase imbalance that can damage motors, drive systems, and other three-phase equipment. Built to operate in industrial and commercial panels up to 600V, the FA36030CBA integrates smoothly with existing Square D installations, providing a reliable, straightforward upgrade path when you’re modernizing or restoring critical power infrastructure.

Ideal use scenarios:

• Maintenance and service upgrades for 3-phase machinery and motors
• Retrofits to bring older panels up to current protection practices
• Replacement in 3-pole, 600V distribution panels to minimize downtime

Key specifications at a glance:

• Amperage: 30A
• Poles: 3-Pole
• Voltage: 600V
• Part number reference: FA36030CBA
• Recommended scenarios: Maintenance, Retrofit, Replacement

Compatibility and fitment guidance: Always confirm the breaker’s fit and ratings before ordering. The FA36030CBA part number is the most reliable reference for identifying compatibility with your panel, wiring diagram, and catalog. If you’re cross-referencing for a retrofit or replacement, verify the current rating, pole configuration, and voltage class to ensure a seamless swap without rewiring.
