PDG21M0125TFFJ - 125 Amp Circuit Breaker

PDG21M0125TFFJ - 125 Amp Circuit Breaker

The Eaton PDG21M0125TFFJ is a 125-amp, 1-pole molded case circuit breaker from the Power Defense line. It's a Frame 2 breaker with a 65kA AIC rating at 277 VAC, fixed trip, and line and load lugs. This combination makes it a good fit for compatible electrical distribution equipment that requires those specific ratings. The breaker measures 1.38 inches high, 6 inches wide, and 3.5 inches deep. If you're replacing an existing breaker, check the full catalog number and electrical ratings before making the swap. Small differences between breakers can matter, especially when it comes to voltage, interrupting capacity, trip type, and connections.

Where It Works Best

• This breaker makes sense for commercial and industrial electrical applications that specifically call for a 125A, 1-pole breaker with a 65kA rating at 277 VAC. It may be used with compatible power distribution equipment, electrical systems, control equipment, and replacement applications.
  
• For replacement work, don't go by appearance alone. Start with the PDG21M0125TFFJ catalog number, then compare the amperage, poles, voltage, AIC rating, trip type, lugs, and dimensions with those of the breaker being replaced and the equipment requirements. That's a much safer way to determine whether it's the right fit.
