Eaton | PDG23G0125TFFL | Circuit Breaker | 125A | 3-Pole | 600V

Eaton PDG23G0125TFFL is a 125-amp, 3-pole circuit breaker rated for 600V, designed for maintenance, retrofit, and replacement projects where exact specs matter.

When you’re upgrading or refurbishing electrical distribution, this part delivers predictable performance and reliable compatibility with Eaton panels that require PDG-series breakers. Use the part number PDG23G0125TFFL as the primary reference to ensure a perfect fit.

Key specifications

• Amperage: 125 A
• Poles: 3-Pole
• Voltage rating: 600 V

What problems does it solve?

Provides dependable overcurrent protection for three-phase circuits in industrial and commercial settings. The 600V rating supports safe operation in medium-voltage distribution, while the 125A capacity is well-suited for medium-load feeders and motor circuits. The three-pole design ensures simultaneous switching and protection of all phases.

Ideal use cases

• Maintenance and retrofit projects where the existing panel requires PDG-series breakers
• Replacement for failed or worn-out 3-pole, 600V protection devices in commercial machinery, pumps, and conveyors
• New installations within Eaton-compatible electrical systems that demand precise 125A trip capability

Fit, compatibility, and installation tips

Always confirm fit and ratings before ordering. The PDG23G0125TFFL part number is the most reliable reference for compatibility with Eaton equipment. Verify panel labeling, bus connection type, and the intended voltage level (up to 600V) before installation. If in doubt, consult the panel manufacturer’s documentation to ensure the breaker is the correct replacement or upgrade.

Practical tips:

• Keep a spare PDG23G0125TFFL on hand for planned maintenance to minimize downtime.
• Document the exact part number in your asset registry to simplify future replacements.
• Store unused breakers in their original packaging to prevent corrosion or contamination.
