Westinghouse | RK3175 | Circuit Breaker | 175A | 3-Pole | 600V

Meet the Westinghouse RK3175 circuit breaker—a 3-pole protective device engineered for 600V systems and a 175A rating. This unit is purpose-built for maintenance, retrofit, and replacement projects where a precise, compatible breaker is required to keep three-phase power safely flowing in your facility.

Key specifications

• Amperage: 175 A
• Poles: 3-Pole
• Voltage rating: 600 V
• Reference for compatibility: Part number RK3175

Why this RK3175 matters for your panels

In three-phase distributions, a 3-pole breaker like the RK3175 provides coordinated protection across all legs, helping prevent overloads and misbalance that can stress equipment. The 175A rating is a practical choice for mid-range feeders and branch circuits in commercial and light-industrial environments.

Because the part number RK3175 is the defining reference, use it to confirm fit with your panel model, bus arrangement, and manufacturer listing. Always verify that the breaker’s amperage, voltage, and pole configuration align with your installation before ordering.

Ideal use cases

This breaker shines in retrofit and replacement projects where a panel requires a 3-pole, 600V device with a 175A capacity. Typical applications include service entrance panels in warehouses, manufacturing floors, or data center infrastructure that depend on reliable, coordinated protection for three-phase electrical feeders.

Beyond replacements, it’s a solid option for planned maintenance where you’re refreshing older protective devices to restore safe, code-compliant operation.

Tip: Keep documentation handy—the RK3175 is the best compatibility reference. Match it against your panel’s listed parts, and confirm ratings before purchase to minimize downtime.
