HFJ437175 | Circuit Breaker | 175A | 3-Pole | 480V

HFJ437175 is an industrial-grade circuit breaker engineered for 480V three-phase systems. With a precise 175A rating and a 3-pole configuration, this unit delivers reliable overcurrent protection and synchronized trip across all phases, helping safeguard equipment and maintain stability in demanding environments.

Key specifications

• Amperage: 175A
• Poles: 3-Pole
• Voltage: 480V

Note: Confirm fit and ratings before ordering. The part number HFJ437175 is the best reference for compatibility with your panel and system. If your equipment labeling references this exact part number, you’re aligned for a straightforward replacement or retrofit.

Ideal use cases

• Maintenance and service of existing 480V, 3-phase power distribution networks
• Retrofit projects to upgrade aging gear or to meet updated safety standards
• Replacement for failed or obsolete breakers in industrial panels
• Spare provision for field technicians to minimize downtime during outages

Why this matters for your system

Selecting a 175A, 3-pole breaker for 480V service ensures coordinated protection across all phases, reducing the risk of partial faults and enabling a safer, cleaner shutdown when faults occur. This targeted specification is particularly valuable in motor control centers, manufacturing lines, and heavy machinery feeds where precise protection and quick replacement are critical.

Practical procurement and installation tips

• Always verify that your panel and conductors are rated for 480V and support a 3-pole breaker with the same amperage
• Use the exact HFJ437175 part number as your cross-reference to avoid mismatches
• Engage a licensed electrician for installation to ensure proper wiring, alignment, and safety compliance
• Keep a spare HFJ437175 on hand to reduce downtime during maintenance or retrofit projects
