Square D FAL34030G 30A 3-Pole 480 V Circuit Breaker

The Square D FAL34030G is a purpose-built 30 A, 3-pole circuit breaker designed for demanding industrial power systems. Rated at 480 V, this device provides reliable overcurrent protection across all three phases, helping prevent equipment damage, wiring insulation stress, and unplanned downtime in your distribution panels. Identified by part number FAL34030G, it’s the exact replacement or addition you need for compatible Square D installations.

Key benefits that matter in real-world setups

• Three-pole protection—simultaneous interruption on all three phases ensures balanced fault isolation, reducing the risk of phase-to-phase faults and cascading trips in three‑phase systems.
• 480 V rating—designed for standard industrial high-voltage panel boards and feeders, making it suitable for manufacturing lines, process equipment, and large-scale distribution.
• 30 A operating current—provides targeted protection for circuits and equipment sized around a 30 A load, helping you coordinate protection with upstream devices and minimize nuisance trips.
• Brand compatibility—built to work within Square D installations and the FAL-series ecosystem, helping you maintain consistent performance and reliable splicing in compatible enclosures.
• Durable, field-ready design—engineered for steady operation in industrial environments, with the confidence that comes from a proven Square D protection solution.

Ideal applications and use cases

• Three-phase motor feeders for manufacturing equipment and conveyors up to 30 A per phase.
• Main distribution panels in facilities that operate 480 V three-phase networks, needing robust fault isolation.
• HVAC and process equipment power distribution where reliable protection reduces downtime and wiring stress.
• Upgrade or retrofit projects where a precise 30 A, 3-pole device is required to match existing Square D panel configurations.

Practical installation and performance notes

Before installation, verify that your system operates at 480 V and that the circuit requires three-pole protection. Use the FAL34030G in compatible Square D panels and enclosures designed for FAL-series breakers, and align with your local electrical codes and enclosure manufacturer specifications. When replacing or adding this breaker, ensure conductors and lugs are sized appropriately for 480 V service and that the device is mounted securely to maintain dependable trip performance. After any fault, assess the affected circuit, reset only after locating and correcting the cause, and re-energize following standard Lockout/Tagout procedures.
