PDG23G0125TFFJ - 125 Amp Circuit Breaker

PDG23G0125TFFJ - 125 Amp Circuit Breaker

The Eaton PDG23G0125TFFJ is a 125-amp, 3-pole molded-case circuit breaker from the Power Defense line. It's a practical choice for commercial and industrial electrical systems that need reliable circuit protection without an overly complicated setup. This Frame 2 breaker has a fixed trip, line and load lugs, and an interrupting rating of 35 kA at 480 VAC. That combination makes it suitable for a range of power distribution and equipment protection applications that require a 125A, three-pole breaker. If you're replacing an existing breaker, checking the full PDG23G0125TFFJ part number is important—the amperage is only one piece of the match. Pole count, frame size, trip configuration, voltage, interrupting rating, and connection type should also be verified before installation.

Key Features and Benefits

• 125-amp rating for compatible commercial and industrial circuits
• 3-pole configuration for applications requiring three-pole circuit protection
• 35kA interrupting rating at 480 VAC for handling substantial fault-current levels within the breaker's specified rating
• Fixed trip design provides consistent protection without adjustable trip settings
• Frame 2 Power Defense construction offers a compact solution for compatible electrical equipment
• Line and load lugs provide connection points on both sides of the breaker
• Designed for applications where dependable overload and short-circuit protection is needed

Material Compliance and Certifications

• The PDG23G0125TFFJ Power Defense circuit breaker is designed to meet applicable electrical safety and performance requirements. The product is RoHS-compliant and associated with recognized standards and certifications, including UL 489, CSA, IEC 60947-2, and CCC.
• Certification requirements can vary by equipment and application, so the applicable ratings and approvals should always be checked against the installation requirements.

Where It Works Best

• This breaker makes sense in commercial buildings, industrial facilities, power distribution equipment, machinery, control systems, and other compatible three-phase electrical applications that call for a 125A, three-pole molded-case circuit breaker.
  
• The 35 kA rating at 480 VAC is particularly important in systems where the available fault current requires that level of interrupting capacity. For replacement work, don't rely on the 125A rating alone. Check the existing breaker and equipment requirements against the complete PDG23G0125TFFJ specifications, including the frame, poles, voltage, A.I.C. rating, trip style, and lug configuration.
