Westinghouse | HFD3045W | Circuit Breaker | 3-Pole

Meet the Westinghouse HFD3045W 3-Pole Circuit Breaker—built for reliable protection in three-phase electrical systems. This unit is specifically geared for maintenance, retrofit, and replacement projects where exact specs matter, helping you preserve panel integrity and circuit safety without guesswork.

• 3-Pole configuration supports multi-conductor circuits, delivering coordinated protection across three lines for balanced, three-phase applications.
• Ideal for maintenance, retrofit, and replacement tasks where matching specs are required—keep your panel's protection consistent with the original design.
• Best compatibility reference the part number HFD3045W—use this to verify fit with your Westinghouse panel and related equipment.
• Important compatibility check confirm the exact fit and ratings before ordering to avoid mismatches and ensure safe, reliable operation.

Why this matters: using the correct 3-pole breaker ensures comprehensive protection for all conductors in a 3-phase setup, reducing the risk of undetected faults and helping maintain electrical system reliability over time. The HFD3045W designation provides a precise, trackable reference that aligns with Westinghouse panel configurations, so you’re not guessing about compatibility.

Who benefits most: electricians, facilities managers, and homeowners performing panel maintenance or upgrades where a direct, drop-in replacement is required. If you’re upgrading an older installation or restoring a panel’s original protection profile, this 3-pole breaker offers a clear path to continuity and safety.

Practical use and tips:

• Always verify the panel labeling and the branch-circuit rating to ensure the HFD3045W matches the intended protection level.
• Plan for a clean installation: power down the main, verify absence of voltage, and loosely mount before final wiring to confirm clearance and fit.
• Keep the part number handy during ordering or service calls—the HFD3045W reference minimizes compatibility questions and accelerates replacements.
