Square D FDA34020 Circuit Breaker, 20A, 3-Pole, 480V

Engineered by Square D, the FDA34020 circuit breaker delivers reliable protection for industrial electrical service, maintenance, and replacement projects. With a 20-amp rating across 3 poles and a 480-volt maximum, it is designed for three-phase power configurations common in manufacturing floors, processing lines, and heavy machinery panels.

Key features and why it matters:

• Part Number: FDA34020 — use this exact identifier to verify fit with your panel and application requirements.
• Brand/Manufacturer: Square D — trusted in industrial environments for durability and consistent performance.
• Amperage: 20 A — tuned to protect circuits feeding motors, conveyors, and control equipment without nuisance trips.
• Poles/Configuration: 3 Poles — suitable for 3-phase systems, ensuring balanced protection across all conductors.
• Voltage: 480V — intended for industrial power distribution setups that run at high voltage levels.

Applications and use cases:

• New installations in 3-phase 480V systems where robust, trip-capable protection is required.
• Maintenance replacements in existing panels to restore reliable fault protection and system uptime.
• Industrial environments such as manufacturing lines, process equipment, and heavy-duty control circuits where consistent performance matters.

How this differs from general-purpose breakers: this FDA34020 is built for the demanding needs of industrial service and relocation projects, with compatibility confirmed by its part number and application requirements.
