Square D FA34015G 15A 3-Pole 480 V Circuit Breaker

Meet the Square D FA34015G 15A 3-Pole 480 V Circuit Breaker — a purpose-built protector for demanding 3‑phase systems. This unit is configured to interrupt all three conductors in a 480 V environment, delivering reliable, coordinated protection for your industrial or commercial electrical distribution.

• Current rating: 15 A
• Poles: 3
• Voltage rating: 480 V
• Part number: FA34015G
• Brand: Square D

Designed specifically for 3‑phase applications, the FA34015G helps safeguard motors, drives, pumps, and other high‑load equipment found in manufacturing, facilities management, and HVAC systems. By cutting power across all three phases when faults occur, it minimizes risk and protects both equipment and personnel in high‑voltage environments.

Why choose this Square D circuit breaker? It’s engineered to integrate smoothly with Square D panels and existing infrastructure, providing consistent performance in 480 V distribution networks. Its 15 A rating is ideal for circuits that require precise protection without nuisance trips, while the 3‑pole design ensures synchronous disconnection of all phases for safer shutdowns.

Ideal use cases include:

• 3‑phase motor protection in industrial machinery and conveyors
• Electrical feeders and service panels in facilities with 480 VAC distribution
• Control circuits and branch circuits that require robust overcurrent protection

Practical tips for deployment:

• Verify that your system operates at or below 480 V and uses three conductors to leverage the full 3‑pole protection
• Ensure compatibility with your Square D enclosure and wiring scheme for seamless replacement or upgrade
• Document the FA34015G part number for future maintenance and ordering consistency
