Where It Works Best

• This breaker makes the most sense in commercial and industrial electrical systems that require a 125A, 1-pole, fixed-trip molded-case circuit breaker with the corresponding Power Defense Frame 2 configuration. Typical uses may include power distribution equipment, industrial machinery, control equipment, facility electrical systems, and maintenance or replacement projects.
• If you're replacing an existing breaker, don't rely on amperage alone. Check the full PDG21G0125TFFL part number along with the pole count, interrupting rating, trip type, connections, dimensions, and other equipment requirements. Two breakers can look similar and still have important differences that affect whether they're right for the job.
