Square D FA34030G 30A 3-Pole 480 V Circuit Breaker

The Square D FA34030G 30A 3-Pole 480 V Circuit Breaker delivers reliable three-phase protection for demanding industrial environments. Part of Square D's trusted distribution lineup, this unit is built to intercept faults quickly, protect downstream equipment, and simplify panel maintenance.

• Three-pole protection for 480 V systems: disconnects all three phases simultaneously, minimizing fault conditions and protecting equipment from collateral damage.
• 30-amp current rating: precisely matches common motor loads and distribution feeders, reducing nuisance trips while guarding conductors and devices.
• 480 V voltage rating: ideal for industrial controls, manufacturing lines, and large HVAC or pumping applications that run on three-phase power.
• Part Number FA34030G: straightforward sourcing and replacement within existing Square D installations, helping minimize service downtime.
• Durable, industry-grade design: engineered for continuous operation in demanding environments, delivering consistent performance over the life of your panel.

Ideal use cases include motor control centers, distribution panels in manufacturing facilities, large warehouse electrical feeders, and mechanical rooms in data centers where reliable 3-phase protection at 480 V is essential. If you’re upgrading an older panel or building a new 480 V three-phase system, the FA34030G offers a precise, compatible solution that aligns with your Square D ecosystem.

Practical installation notes: verify panel compatibility with the FA34030G and follow the manufacturer's torque specifications for terminal connections. Plan for quick-fault isolation by ensuring the breaker’s trip mechanism matches your protection strategy and that downstream conductors are appropriately rated for 480 V and 30 A. Regular inspection of connections and a documented maintenance schedule will help maximize lifecycle and minimize unexpected outages.
