PDG21M0100TFFL - 100 Amp Circuit Breaker

PDG21M0100TFFL - 100 Amp Circuit Breaker

If you're looking for the Eaton PDG21M0100TFFL, the important details are pretty straightforward. This Power Defense molded case circuit breaker is a 100A, single-pole breaker with an interrupting rating of 65kA at 277 VAC. It's an Eaton Frame 2 design and comes with a fixed trip and load lugs. For contractors, electricians, maintenance teams, and facility managers, that combination makes it a practical option when the job calls for these specific electrical ratings. The breaker measures 1.38 inches high, 6 inches wide, and 3.5 inches deep, so checking the dimensions along with the electrical specifications can help when matching it to existing equipment. Most importantly, don't choose a replacement breaker based on amperage alone. Confirm the part number, pole count, A.I.C. rating, voltage, frame, trip type, connections, and physical dimensions to make sure the PDG21M0100TFFL is right for your application.

Where It Works Best

• The Eaton PDG21M0100TFFL is best suited for compatible commercial and industrial electrical applications that require a 100A, 1-pole molded-case circuit breaker with a 65kA rating at 277 VAC. It may be used with compatible power distribution equipment and other electrical systems where its Frame 2 construction, fixed trip, load lugs, ratings, and dimensions meet the equipment requirements.
  
• If you're replacing an existing breaker, matching PDG21M0100TFFL is a good starting point—but it's worth checking the complete set of specifications. Two breakers can appear similar while having different interrupting ratings, trip configurations, frames, or connection arrangements. Verify the electrical ratings and physical compatibility before installation.
