PDG21G0090TFFJ - 90 Amp Circuit Breaker

PDG21G0090TFFJ - 90 Amp Circuit Breaker

The Eaton PDG21G0090TFFJ is a 90-amp, single-pole molded case circuit breaker from the Power Defense line. It's a Frame 2 breaker with a 35kA interrupting rating at 277 VAC, a fixed trip, and line and load lugs. If you're replacing a breaker that's already in service, those details matter. A breaker may look similar or have the same amp rating and still not be the right match for the equipment. The PDG21G0090TFFJ measures 1.38 inches high, 6 inches wide, and 3.5 inches deep, giving you another set of measurements to check against your application. This breaker makes sense for maintenance, replacement, or installation work where the system specifically requires its 90A rating, single-pole configuration, voltage rating, interrupting capacity, and connection setup.

Material Compliance and Certifications

• Certification and material compliance requirements can depend on the exact breaker configuration and the application in which it's installed. For that reason, any required listings, certifications, or material compliance information should be verified against the current manufacturer documentation for part number PDG21G0090TFFJ. This avoids assuming that documentation for a similar Power Defense breaker applies to this exact model.

Where It Works Best

• The PDG21G0090TFFJ is intended for compatible electrical systems that call for a 90A, 1-pole molded-case circuit breaker with a 35kA rating at 277 VAC. It's a natural fit for breaker replacement and electrical maintenance work, as well as for retrofit or new installations where the specified ratings match.
