Why this Westinghouse circuit breaker stands out

Designed to fit into compatible Westinghouse panels and systems that require a 3-pole, 110A, 600V protection device, the HFD3110 delivers reliable, balanced protection across all three phases. The 3-pole configuration is ideal for 3‑phase distribution, ensuring that each phase is monitored and protected under the same electrical criteria. The part number HFD3110 is the best reference when checking compatibility with your panel, so verify the fit and ratings before ordering to minimize downtime.

Ideal use cases

• Maintenance: replace aging or failing breakers to restore solid protection in a three-phase panel.
• Retrofit: upgrade or upgrade‑match an existing 3‑pole 110A, 600V feeder circuit within commercial or industrial systems.
• Replacement: swap out worn components in panels that require exact 110A, 3-pole, 600V specifications for continued reliability.

Compatibility and installation guidance

Before purchasing, confirm that your panel accepts the HFD3110 and operates at 600V with 110A circuits. The part number HFD3110 is your most dependable reference for compatibility. Installation should be performed by a qualified electrician, with the power fully de-energized and all necessary safety protocols observed. Keep labeling and system documents handy to ensure the device matches the panel’s ratings and the intended load profile.

Practical benefits you can expect

• Aligned protection across all three phases reduces the risk of uneven loading and tripping.
• Clear specification mapping (110A, 3-Pole, 600V) facilitates accurate project planning and panel matching.
• Reliable, straightforward replacement that minimizes downtime when servicing commercial or industrial distribution panels.
