Square D | FHP16045 | Circuit Breaker | 45A | 1-Pole | 277V

Meet the Square D FHP16045 Circuit Breaker — a precise, plug-in protection device designed for 277V single-pole circuits. With a 45A rating, it interrupts excess current to safeguard wiring and devices in commercial and industrial panels that rely on 277V distribution.

Key advantages:

• Exact fit for FHP-series panels: The part number FHP16045 is the definitive reference for compatibility, making maintenance, retrofit, or replacement straightforward.
• Single-pole protection: Ideal for single-phase circuits, reducing panel space while delivering reliable overcurrent protection.
• 277V operation: Suitable for systems that use 277V lighting, machinery, or control circuits common in commercial environments.

Use cases you’ll appreciate:

• Replacing a failed 1-pole 277V breaker in an existing Square D panel to restore protected circuits without rewiring.
• Retrofit projects where your panel specification calls for a 45A 1-pole breaker with 277V rating.
• Maintenance tasks that require a trusted, known-good component from Square D’s FHP family.

Why this matters:

• Reliable overcurrent protection ensures that wires stay within their temperature ratings and connected devices avoid damage during faults.
• Using the correct part number reduces the risk of incompatibility, downtime, and mis-matched ratings during critical repairs.

Practical tips for installation and ordering:

• Always confirm fit and ratings before ordering by cross-checking the FHP16045 part number against your panel’s documentation.
• Have the exact panel model and voltage requirements on hand when shopping to ensure seamless replacement.
• Store spares in a cool, dry location to maintain performance and reliability over time.
