Why this 3-Pole, 480V breaker matters

In a three-phase distribution setup, a 3-pole breaker like this one interrupts all three live conductors simultaneously, helping protect connected equipment and maintain system balance. The 60A rating suits moderate-to-heavy loads in commercial and light industrial applications, enabling effective protection for motors, feeders, and other 3-phase circuits without over-tripping under normal startup surges.

Ideal for

• Maintenance projects where a precise 60A, 3-pole/480V solution is required
• Retrofits upgrading protection in existing 3-phase, 480V panels
• Replacement scenarios where exact part matching ensures compatibility with current electrical infrastructure

Compatibility & ordering tips

To ensure a correct fit, verify your panel’s specifications and confirm the exact match with the FA340601021 part number. The part number is the most reliable reference for compatibility, reducing the risk of mismatched ratings or pole configurations in your 480V, three-phase system.

Installation and best practices

When installing, follow your panel’s installation guidelines and safety procedures. Power down the distribution system before servicing, ensure proper alignment and seating of the breaker, and use the panel’s recommended torque and mounting practices. After installation, perform standard functional checks to confirm proper tripping behavior and circuit isolation.

Designed for professionals who need dependable, spec-accurate protection for 480V, 60A, 3-pole circuits, the Square D FA340601021 delivers consistent performance in demanding industrial and commercial environments.
