Meet the Square D FJA140205 Circuit Breaker — a purpose-built, plug-in 20A solution designed to protect 277V circuits with precision and ease. This single-pole unit shines in maintenance, retrofit, and replacement projects where matching specs matters, delivering reliable performance without the guesswork.
Key specifications at a glance
- Amperage: 20 A
- Poles: 1-Pole
- Voltage: 277V
- Interrupting Capacity: 65kA
- Mounting: Plug-In
Why this matters: a 65kA interrupting rating means the breaker is designed to safely interrupt high fault currents, protecting both the panel and connected equipment. The plug-in design simplifies installation — ideal for quick swaps in compatible Square D panels, reducing downtime during servicing and upgrades.
Who it’s for and practical uses
- Facility managers and electricians performing maintenance on 277V lighting circuits, control panels, or small equipment feeders.
- Techs conducting retrofits or replacements in existing Square D panels that require a 1-pole, 20A device with a plug-in footprint.
- Projects where exact part matching is critical — the FJA140205 part number is the best reference for compatibility.
Installation and compatibility tips
- Always isolate power before attempting installation. Verify the panel accepts plug-in breakers in the same family and series.
- Confirm the part number (FJA140205) matches your panel and circuit requirements to ensure proper fit and ratings.
- When replacing an existing breaker, compare the old unit’s specifications with this model: 20A, 1-Pole, 277V, 65kA. If they align, this plug-in replacement should snap into place without further modification.
Designed for dependable protection in commercial and light industrial settings, this Square D plug-in breaker helps you achieve quick, reliable upgrades with confidence. Use the part number FJA140205 to verify compatibility, and count on a straightforward installation that keeps your electrical system safeguarded and up to code.
