Westinghouse | HFB3480ML | Circuit Breaker | 3-Pole | 600V | 25kA

Meet the Westinghouse HFB3480ML Circuit Breaker—a robust 3-pole protective device designed to keep multi‑circuit systems safe in demanding environments. Rated for 600V operation with a 25kA interrupting capacity, it’s built for reliability in maintenance, retrofit, and replacement projects where precise specifications matter.

Key specifications

• Poles: 3-Pole
• Voltage: 600V
• Interrupting Capacity: 25kA

This breaker is purpose-built for three‑phase distribution, providing synchronized protection across all legs of a circuit. Its form factor and ratings align with panels and assemblies that reference the HFB3480ML, making it a practical choice for upgrading protection without changing your panel architecture.

Ideal use cases:

• Maintenance: replace worn or aging breakers in 3‑pole 600V systems to restore stable protection.
• Retrofit: upgrade legacy panels to meet current safety standards without reconfiguring the entire electrical cabinet.
• Replacement: swap-in compatible units that require the HFB3480ML part reference for the exact fit and rating.

Why choose Westinghouse for this job? The Westinghouse HFB3480ML is backed by a long-standing reputation for dependable overcurrent protection. By matching the exact part number, you minimize compatibility risk and avoid unnecessary panel modifications. This dedicated 3‑pole design ensures balanced protection across all three phases, helping protect motors, drives, and other heavy loads from short-circuit and overload conditions.

How to ensure you’re buying the right unit:

• Always verify fit and ratings before ordering. The part number is the best reference for compatibility.
• Check your panel documentation and any manufacturer compatibility lists for 3‑pole 600V assemblies.
• Confirm that your system requires a 25kA interrupting rating to match your fault-current potential.
