The UQFB225-3 is a rugged industrial circuit breaker designed to safeguard demanding 3‑phase power systems. With a 225 A rating, a 3‑pole configuration, and 240 V operation, it delivers reliable overcurrent protection where performance and compatibility matter most.

Ideal for maintenance, retrofit, and replacement projects, this unit is built to match exact specifications. The part number UQFB225-3 serves as the definitive reference for compatibility, helping you confirm fit before you order and reducing the chance of mismatches in your enclosure or panel.

Key specifications

• Amperage: 225 A
• Poles: 3‑Pole
• Voltage: 240 V

Why this matters in practice

In three‑phase power systems, a 3‑pole 240 V circuit breaker provides balanced protection across all phases, guarding motors, feeders, and control circuits from overloads and short circuits. The 225 A rating gives ample headroom for standard startup surges common in motor-driven equipment, while still delivering precise protection diagnostics and clear tripping behavior when limits are exceeded.

Use cases and ideal buyers

• Electrical technicians performing panel maintenance or upgrades who need an exact 225 A, 3‑pole, 240 V replacement
• Facilities engineers retrofitting legacy systems to modern protection standards
• Project teams selecting matching components for new builds that replicate existing 3‑phase, 240 V distribution

Practical guidance for ordering and installation

Before purchasing, verify the fit and ratings on your specific panel or enclosure. Rely on the part number UQFB225-3 as the primary compatibility reference to ensure the unit aligns with your bus configuration, mounting method, and 240 V three‑phase setup. Once installed, confirm that the surrounding wiring, terminations, and protective devices are rated for 225 A and compatible with a 3‑pole 240 V circuit to maintain holistic system protection.

Choosing the UQFB225-3 means prioritizing precise spec alignment, straightforward replacement in older installations, and dependable protection for active, high‑demand networks. If your system requires a 225 A, 3‑pole, 240 V circuit breaker with a clear path to reliable performance, this unit is a well‑matched, purpose‑built solution.
