PDG21G0125TFFJ - 125 Amp Circuit Breaker

PDG21G0125TFFJ - 125 Amp Circuit Breaker

When you're replacing a circuit breaker, getting the details right matters. The Eaton PDG21G0125TFFJ is a 125A, 1-pole molded case circuit breaker from the Global Rated Power Defense family. This Frame 2 breaker has a 35 kA interrupting rating at 277 VAC, a fixed trip, and line and load lugs. It measures approximately 1.38 inches high, 6 inches wide, and 3.5 inches deep. That combination makes it a practical option for compatible electrical distribution equipment where these exact ratings and dimensions are required. Whether you're handling scheduled maintenance, replacing an existing breaker, or working on an electrical system upgrade, it's worth checking the entire specification—not just the amperage. Pole count, interrupting rating, trip style, connections, frame size, and physical dimensions all play a part in determining whether a breaker is the right match.

Key Features and Benefits

• 125A rating for applications requiring 125-amp circuit protection.

Certification and material-compliance information was not provided with the specifications for this listing, so we don't want to make claims that can't be verified.
  

Where It Works Best

• The PDG21G0125TFFJ is intended for compatible electrical distribution applications calling for a 125A, 1-pole molded-case breaker with a 35kA rating at 277VAC. It may be suitable for commercial and industrial electrical systems, facility maintenance work, equipment repairs, and replacement projects where the original equipment specifications call for this particular breaker configuration.
• Already have a breaker you're trying to replace? Start with the full PDG21G0125TFFJ part number, then compare the ratings and physical configuration. A breaker being 125 amps doesn't automatically make it interchangeable with another 125-amp model. Check the pole count, voltage, interrupting rating, frame, trip configuration, lug arrangement, dimensions, and compatibility with the equipment before installation.
• For applications that specifically call for these specifications, the Eaton PDG21G0125TFFJ 125A circuit breaker offers a simple, clearly defined solution for circuit protection.
