With a 1600A rating, a 3‑pole configuration, and a 600V maximum voltage, this unit delivers reliable overcurrent protection for large motors, feeders, and distribution panels in industrial environments.

Key specifications

• Amperage: 1600A
• Poles: 3‑Pole
• Voltage: 600V
• Part number: PB31600PRF
• Applications: suitable for maintenance, retrofit, and replacement needs where matching specs are required
• Compatibility note: Confirm fit and ratings before ordering; the part number is the best reference for compatibility

What makes this breaker stand out

Designed for serious service, the PB31600PRF provides consistent protection across all three phases, helping prevent damage from overcurrent events in high‑load environments. Its 600V rating aligns with common industrial power standards, making it a practical choice for retrofit projects, panel upgrades, or replacements where exact specifications must be matched.

Ideal use cases

• Retrofit projects in existing switchgear where a 1600A, 3‑pole, 600V breaker is required
• Replacement in heavy‑duty distribution panels for large feeders and motors
• Maintenance planning where a precise part reference (PB31600PRF) ensures compatibility

Practical guidance for purchasing and installation

Because proper fit and ratings are critical for safe operation, always verify that the breaker’s amperage, pole count, and voltage align with your panel and service conditions. Use the PB31600PRF part number as the primary compatibility reference to match the exact Eaton specification in your enclosure. When in doubt, cross‑check with your system documentation and purchase the unit intended for replacement or retrofit in your existing 3‑phase configuration.
