PDG21M0125TFFL - 125 Amp Circuit Breaker

PDG21M0125TFFL - 125 Amp Circuit Breaker

If you need an Eaton PDG21M0125TFFL, the important thing is making sure every rating matches your application—not just the amperage. This Power Defense molded-case circuit breaker is a Frame 2, 1-pole breaker rated at 125 amps, with an interrupting rating of 65 kA at 277 VAC. It comes in a fixed-trip configuration with load lugs and measures approximately 1.38" high x 6.0" wide x 3.5" deep. That combination makes the PDG21M0125TFFL a good fit for compatible commercial and industrial electrical equipment calling for these exact specifications. It's also worth checking the full part number when replacing an existing breaker. Two breakers can appear similar at first glance while differing in frame, trip style, interrupting rating, or connection setup.

Key Features and Benefits

Material Compliance and Certifications

• Specific material compliance information and certification details were not included in the available specifications for the PDG21M0125TFFL. If your project requires particular listings, approvals, environmental declarations, or material standards, check the manufacturer's documentation for this exact part number. This is especially important when a breaker is specified for a facility or installation subject to defined regulatory requirements.
  

Where It Works Best

• The Eaton PDG21M0125TFFL makes sense for commercial, industrial, maintenance, and replacement applications that require a 125A, 1-pole molded-case circuit breaker with a 65kA rating at 277 VAC. It can be particularly useful when replacing an existing Power Defense breaker and the equipment calls for the same Frame 2, fixed-trip, and load-lug configuration.
  
• A quick word about breaker selection: 125A alone isn't enough to establish compatibility. Check the complete part number, pole count, voltage, A.I.C. rating, frame, trip type, lug configuration, and physical dimensions. Matching those details before installation is far more useful than choosing a breaker simply because it looks like the one being replaced.
