Square D | FCP34070 | Circuit Breaker | 3-Pole | 480V

Meet the Square D FCP34070, a purpose-built 3-pole circuit breaker rated for 480V that’s designed to excel in maintenance, retrofit, and replacement scenarios. When your project requires exact specifications and a reliable, compatible part, this unit delivers the precise fit you need to keep critical electrical systems protected and operating smoothly.

Key advantages

• Exact 3-pole, 480V design — tailored for three-phase electrical environments and high-voltage distribution.
• Part number FCP34070 — serves as the clearest compatibility reference for a seamless replacement or retrofit.
• Versatile use cases — ideal for routine maintenance, panel retrofits, and straightforward replacements where matching specs matters.
• Square D reliability — engineered to integrate smoothly with Square D panels and systems for predictable, durable protection.

Fit, compatibility, and selection

Before ordering, verify the fit and ratings against your equipment documentation. The part number FCP34070 is the most reliable reference for compatibility, so cross-check it with your panel model, the 3-pole configuration, and the 480V rating. If you’re reconfiguring a three-phase circuit or replacing an aging device, this unit preserves the original protection characteristics and ensures consistent trip behavior.

Ideal use cases

• Upgrading legacy panels and electrical rooms that operate on 480V three-phase power.
• Retrofit projects where a like-for-like replacement minimizes rewiring and downtime.
• Scheduled maintenance or emergency replacements in control cabinets and power distribution panels that require a precise, known-good 3-pole device.

Practical guidance for buyers

• Confirm panel compatibility by matching the exact part number (FCP34070) to your model and filing a quick check of pole count (3) and voltage (480V).
• Consult your panel’s documentation to ensure the breaker’s configuration aligns with current wiring and safety requirements.
• Plan for spares: keeping an exact-fit replacement on hand can reduce downtime during maintenance windows or emergency outages.
