NFJ434175 | Circuit Breaker | 175A | 3-Pole | 480V

NFJ434175 is a purpose-built industrial circuit breaker crafted for 480V three-phase power, delivering a precise 175A rating in a robust 3-pole configuration. Built for maintenance, retrofit, and replacement projects, this unit is designed to match exact specs so you can protect critical equipment and keep your electrical system running smoothly.

Key specifications

• Amperage: 175A
• Poles: 3-Pole
• Voltage: 480V
• Part number reference: NFJ434175

What makes NFJ434175 unique

Unlike generic breakers, NFJ434175 is tailored for industrial environments that rely on stable three-phase protection at high voltage. Its 3-pole design ensures synchronized disconnection across all phases, helping to prevent arc faults and uneven load conditions. The 175A rating is specifically suited for feeders and circuits where moderate to heavy current drive is common, offering dependable protection without unnecessary nuisance trips. The part-number-centric approach helps technicians confirm compatibility quickly, reducing downtime during replacements and retrofits.

Ideal use scenarios

• Replacement in existing 3-pole, 480V panels where the NFJ434175 matches the original specifications
• Retrofit projects upgrading feeders or motors that require a 175A, 3-phase protection scheme
• Maintenance cycles for industrial equipment that operates on 480V systems

How to verify compatibility and maximize value

Important: confirm fit and ratings before ordering. Use the part number NFJ434175 as the primary compatibility reference, and compare it against your panel’s model and intended circuit rating. If your system operates on 480V three-phase power and demands a 175A, 3-pole protective device, this breaker is designed to align with those specifications and performance expectations.

Practical tips for installation and ongoing protection

• Before replacement, inspect the panel labeling to ensure 3-pole, 480V operation and a 175A rating align with your circuit requirements.
• Handle the breaker with standard safety procedures for energized systems; verify de-energization and lockout/tagout practices prior to replacement work.
• Keep documentation that references NFJ434175 for future maintenance, audits, and compatibility checks.
• Store spare units in a controlled environment to preserve conductive surfaces and mechanical integrity for reliable immediate replacement.

Bottom line: If your industrial setup relies on a 3-pole, 480V distribution with a 175A demand, NFJ434175 offers targeted, compatible protection. Its part-number specificity supports fast, accurate replacements, minimizing downtime and ensuring your three-phase system stays safeguarded against overcurrent conditions. Add this unit to your cart when the specifications match your panel and you’re planning a precise, reliable retrofit or replacement solution.
