PDG21M0080TFFL - 80 Amp Circuit Breaker

PDG21M0080TFFL - 80 Amp Circuit Breaker

The Eaton PDG21M0080TFFL is an 80-amp, 1-pole molded-case circuit breaker from the Power Defense line. It's a Frame 2 breaker with a 65 kA interrupting rating at 277 VAC, providing the capacity needed for compatible commercial and industrial electrical systems where higher available fault current is a consideration. This model uses a fixed trip and includes load lugs, so you're getting a straightforward breaker configuration without adjustable trip settings. Size is another useful consideration. The PDG21M0080TFFL measures approximately 6 inches high, 1.38 inches wide, and 3.5 inches deep, providing substantial circuit protection in a relatively compact package. If you're replacing a breaker already in service, matching the full catalog number is important—not just the 80A rating. Pole count, A.I.C. rating, voltage, trip style, dimensions, and connections all play a part in determining whether a breaker is right for the equipment.

Key Features and Benefits

• 80-amp rating for compatible circuits requiring 80-amp overcurrent protection.
• Single-pole design for equipment requiring a 1-pole breaker configuration.
• Rated 65kA at 277 VAC, providing high interrupting capacity for its specified voltage.
• Fixed-trip configuration keeps the setup simple, with predetermined trip characteristics.
• Load lugs included for load-side conductor connections.
• Frame 2 Power Defense design provides a compact footprint for compatible equipment.
• At just 1.38 inches wide, the breaker doesn't take up more room than necessary.
• Suitable for a range of compatible commercial and industrial power distribution applications.

Material Compliance and Certifications

• The Power Defense global molded-case circuit breaker family is designed around recognized electrical safety standards and international market requirements. Comparable Power Defense PD2 Global Frame 2 breakers are identified by Eaton as RoHS-compliant, with certifications and approvals including UL 489, CSA, IEC 60947-2, and CCC.
• Certification can depend on the exact breaker configuration. For that reason, the markings and certifications on the PDG21M0080TFFL should be checked against the equipment and application requirements before installation.
  

Where It Works Best

• The PDG21M0080TFFL is a practical fit for compatible commercial and industrial electrical systems that require an 80A, single-pole molded-case circuit breaker with a 65kA rating at 277 VAC. Depending on the equipment specifications, this can include electrical distribution equipment, panels, machinery, and control applications.
  
• It's also worth considering when space is tight. With a width of approximately 1.38 inches, this Frame 2 breaker provides the required electrical ratings in a compact package.
  
• Replacing an existing circuit breaker? Match the entire PDG21M0080TFFL part number whenever possible. Two breakers can share the same amperage while differing in pole count, interrupting capacity, voltage rating, trip configuration, connections, or physical size. Checking those details before installation is the safer way to determine compatibility.
