PDG21M0045TFFL - 45 Amp Circuit Breaker

PDG21M0045TFFL - 45 Amp Circuit Breaker

The Eaton PDG21M0045TFFL is a 45A, 1-pole molded case circuit breaker from Eaton's Power Defense line. It's a Frame 2 breaker with a fixed trip, load lugs, and an interrupting rating of 65 kA at 277 VAC. That combination makes it a good fit for compatible electrical systems where a 45-amp breaker and higher fault-current protection are required. The breaker measures 1.38 inches high, 6 inches wide, and 3.5 inches deep, making it relatively compact while still providing the electrical ratings required for demanding commercial and industrial applications. If you're replacing an existing breaker, the details matter. Check the PDG21M0045TFFL part number, along with the amperage, number of poles, A.I.C. rating, trip style, lug configuration, and physical size, to ensure it matches the equipment you're working with.

Material Compliance and Certifications

• The PDG21M0045TFFL is part of Eaton's globally rated Power Defense molded case circuit breaker family. Specific certifications and material compliance requirements can vary depending on the exact breaker configuration and application. When a job requires a particular UL, CSA, IEC, RoHS, or other regulatory designation, verify the certification for this exact catalog number using the breaker label and current manufacturer documentation.

Where It Works Best

• The Eaton PDG21M0045TFFL circuit breaker is suited for compatible commercial and industrial electrical distribution systems that require a 45A, single-pole molded-case breaker. Its 65 kA rating at 277 VAC is particularly useful in applications where the available fault current requires this level of interrupting capacity.
• It's also a practical option for maintenance and replacement work involving compatible Power Defense Frame 2 equipment. When replacing a breaker, don't match it by amperage alone. Compare the full part number, pole count, voltage and interrupting rating, fixed-trip configuration, lugs, dimensions, and equipment requirements before installation.
• For the right application, the PDG21M0045TFFL is a straightforward choice: 45 amps, one-pole, fixed-trip, load lugs, and 65 kA interrupting capacity at 277 VAC—the important specifications are easy to identify and verify.
