Product description
Shipping
Square D FY14100A is a compact, reliable 1-pole circuit breaker engineered for 277 V systems. Built to protect single‑pole circuits in commercial panels, this unit carries the part number FY14100A and a current rating of 14100 A, delivering dependable overcurrent protection where 277 V distribution is standard.
- Configuration: 1-pole design for single‑phase protection
- Voltage rating: 277 V, ideal for commercial lighting and auxiliary circuits
- Current rating: 14100 A (as specified for this model)
- Brand and compatibility: Square D family, designed to integrate with compatible panels and devices within the same system
This breaker is purpose-built for environments where 277 V distribution is common—think office buildings, retail spaces, and other commercial facilities. The 1‑pole configuration provides targeted protection for individual branches, helping prevent damage from overloads and short circuits without interrupting other circuits in the panel.
Why choose the Square D FY14100A? It offers familiar operation and proven performance within the Square D ecosystem, reducing the guesswork during panel upgrades or replacements. Its dedicated 277 V rating means you can confidently protect circuits powering lighting, ventilation, and related equipment in commercial environments.
Use cases and scenarios
- Protect a single 277 V lighting run in a commercial hallway or open office space
- Safeguard auxiliary circuits in HVAC or building automation that run on 277 V
- Upgrade a panel where a dedicated FY14100A 1‑pole, 277 V breaker is required for code-compliant circuit protection
Practical considerations
- Verify panel compatibility before replacement to ensure the FY14100A fits the intended 277 V, 1‑pole position
- Follow standard electrical safety practices and consult a qualified electrician for installation or replacement
- Use the model name and part number—Square D FY14100A—to confirm the exact specification when ordering or cross-referencing with spares
