Westinghouse FD3040L 40A 3P 600V Circuit Breaker | AmpState

Westinghouse FD3040L 40A 3P 600V Circuit Breaker delivers dependable overcurrent protection for panelboards, load centers, and electrical distribution networks. Designed for three-phase systems, this 40 amp, 3-pole unit handles up to 600V, offering robust protection for commercial and light industrial applications where reliable shutoff is essential.

Why this breaker stands out for retrofit and maintenance projects:

• Consistent part number for retrofit work: The FD3040L maintains the exact part number your service history and stock rely on, simplifying procurement and reducing the risk of mismatched replacements during upgrades or ongoing maintenance.
• Three‑pole configuration for balanced three‑phase systems: Ensures simultaneous disconnection across all phases, preventing fault conditions that can damage downstream equipment.
• 600V maximum rating with a 40A protection level, tuned for common distribution circuits in commercial environments.
• Easy compatibility support from AmpState: AmpState carries the Westinghouse FD3040L and can help confirm fit for your specific panel model, streamlining ordering and installation.

Ideal use cases and scenarios:

• Retrofit projects where preserving the original part number is crucial for documentation, inventory control, and quick field replacements.
• Maintenance planning with a ready-to-go spare that minimizes downtime during routine service or fault events.
• Replacement in existing Westinghouse panelboards and load centers that require a 3P, 600V, 40A device to maintain consistent protection characteristics.

Practical guidance for purchasing and installation:

• Verify that your panel or distribution setup calls for a 3‑pole, 40A, 600V device in the FD3040L footprint and terminal arrangement.
• If compatibility isn’t immediately clear, reach out to AmpState with your panel model information—they’re ready to help confirm fit and prevent ordering errors.
• Store and handle the breaker in its original packaging in a clean, dry environment to preserve the integrity of the trip mechanism and terminals.

In short, the Westinghouse FD3040L isn’t just a breaker—it’s a turnkey solution for safe, reliable three‑phase protection with streamlined procurement and maintenance workflows.
