HFJ636175 | Circuit Breaker | 175A | 3-Pole | 600V

HFJ636175 is an industrial circuit breaker engineered for reliable protection in power distribution systems. With a 175A rating, a 3-pole configuration, and a 600V operating capability, this unit is purpose-built for demanding environments where precise specifications matter.

Direct-match compatibility for maintenance, retrofit and replacement

Identified by the part number HFJ636175, this breaker is the best reference when you need a precise, drop-in replacement or retrofit. Using the exact part number helps ensure your panel, bus arrangement, and voltage/current requirements align, reducing downtime and the risk of incompatibility.

Key specifications

• Amperage: 175A
• Poles: 3-Pole
• Voltage: 600V

Why this 3-pole, 600V breaker matters

For three-phase networks, a 3-pole breaker delivers synchronized shutoff across all live lines, preserving system safety and minimizing arcing risk. The 600V rating supports higher-power machinery and equipment common in industrial settings, while the 175A capacity suits mid-to-high-load circuits without over‑tripping during normal operation.

Ideal use cases

• Scheduled maintenance on three-phase panels that require a 175A, 3-pole, 600V protection device.
• Retrofit projects where you’re upgrading or modernizing existing electrical infrastructure with a direct-fit component.
• Replacement in industrial control panels, motor control centers, and distribution boards that operate at 600V three-phase power.

Practical verification and installation tips

Before purchasing, confirm fit using the HFJ636175 part number as your primary compatibility reference. Check your panel markings to verify voltage and current ratings, ensure the breaker type matches your distribution equipment, and verify the three-pole configuration aligns with your bus bar layout. Keeping a direct-match HFJ636175 on hand can streamline maintenance cycles and minimize project delays.
