Square D FGA140205 Circuit Breaker, 20A, 1-Pole, 277V

The Square D FGA140205 circuit breaker is built for industrial electrical service, maintenance, and replacement projects where dependable protection matters. With a 20 A rating, a single-pole design, and 277 V operation, it safeguards individual circuits while keeping downtime to a minimum in busy industrial environments.

• Amperage: 20 A
• Poles: 1
• Voltage: 277 V
• Part Number: FGA140205
• Product Type: Circuit Breaker

Key benefits you’ll notice in daily use include precise current protection for 277V circuits—ideal for commercial lighting feeds and industrial distribution—that helps prevent damage from overloads or short circuits. The 1-pole format is perfect for single hot-conductor circuits where a streamlined, straightforward protection device is required, while the rugged Square D design supports reliable, long-term performance in demanding environments.

Why this model stands out for industrial applications: it’s purpose-built for compatibility with industrial panels and equipment that rely on a clear part-number fit and defined electrical characteristics. The FGA140205 designation ensures you’re selecting a device designed for the specific voltage, amperage, and pole configuration your system demands, reducing guesswork during maintenance or replacement projects.

Use cases include protecting individual 277V branch circuits in manufacturing floors, lighting and control feeders in warehouses, or any single-phase distribution path where a 20A breaker is the right protection level. It’s an efficient choice for upgrades, retrofits, and routine panel maintenance where quick, confident part replacement matters.

Compatibility and installation tips:

• Verify fit by part number (FGA140205) against your panel labeling and application requirements.
• Ensure the circuit’s voltage and amperage match the breaker’s 277 V, 20 A, 1-pole specifications before installation.
• Use as a direct replacement in systems designed for this exact part number to maintain consistent protection and panel compatibility.
