PDG23G0045TFFJ - 45 Amp Circuit Breaker

PDG23G0045TFFJ - 45 Amp Circuit Breaker

The Eaton PDG23G0045TFFJ is a 45-amp, 3-pole molded-case circuit breaker in the Power Defense family. This is a Frame 2 breaker with a fixed trip, rated 35 kA at 480 VAC, and it comes with line and load lugs. Its overall dimensions are 4.19" H x 6.0" W x 3.5" D. If you're replacing a breaker already in a panel or piece of equipment, the full part number is the first thing to check. After that, compare the electrical ratings and physical size. The PDG23G0045TFFJ is specifically a 45A, three-pole breaker, so it's important not to match it based on appearance or frame size alone. For applications that call for these exact specifications, it's a straightforward Power Defense breaker without extra features you may not need.

Material Compliance and Certifications

• The PDG23G0045TFFJ is identified as a global-rated Power Defense circuit breaker. If a job requires specific certifications, listings, or material compliance documentation, those details should be verified against the manufacturer's documentation for this exact catalog number. It's worth doing that check rather than assuming every breaker in the same product family carries the same approvals.

Where It Works Best

• The PDG23G0045TFFJ is intended for compatible electrical distribution applications requiring a 45-amp, 3-pole molded-case breaker with a fixed trip and 35 kA rating at 480 VAC. That can include commercial and industrial electrical equipment where these ratings and the Frame 2 configuration are specified.
• For replacement work, take a minute to compare what's already installed. Look at the entire part number, not just the 45A rating. Pole count, interrupting rating, trip type, dimensions, and lug configuration matter too. If those details don't match, don't assume the breaker is interchangeable simply because it looks similar.
