Schneider Electric FA14040A 14040A 1-Pole 277 V Circuit Breaker

Schneider Electric FA14040A 14040A 1-Pole 277 V Circuit Breaker is your go-to solution for dependable overcurrent protection in commercial and light industrial electrical setups. With the part number FA14040A, this single-pole breaker is engineered to safeguard 277-volt circuits, helping you prevent damage from overloads and short circuits while keeping critical systems running smoothly.

• Part Number: FA14040A
• Pole: 1-Pole
• Voltage Rating: 277 V
• Current Rating: 14040 A
• Application: Overcurrent protection for 277 V circuits in commercial panels

Why this matters for your electrical system: a single‑pole 277 V circuit breaker like the FA14040A acts as the first line of defense against electrical faults. When excess current or a fault occurs, it trips quickly to isolate the affected circuit, reducing the risk of equipment damage, electrical fires, and unnecessary downtime. This precise protection is especially important for lighting, control, and small-machinery loads that commonly run on 277 V in commercial environments.

What sets it apart

• Dedicated 277 V protection: Specifically designed for single-pole protection in 277 V circuits, aligning with common commercial power distribution configurations.
• Clear identification: The FA14040A labeling makes it easy to verify correct replacement parts during maintenance or upgrades.
• Reliable Schneider Electric lineage: Part of a trusted family of circuit protection devices known for consistent performance and straightforward installation.

Ideal use cases

• 277 V lighting circuits in office buildings, schools, and retail spaces
• Control circuits for HVAC equipment, fans, and conveyors operating at 277 V
• Panelboard upgrades or replacements where a 1-pole 277 V breaker is required

Practical tips for installation and use: verify that your panel supports 277 V single-pole protection, and ensure the current rating matches the load characteristics you’re protecting. Keep FA14040A on hand for quick replacements to minimize downtime, and pair it with compatible Schneider Electric components to maintain consistent electrical protection across the system.
