PDG21G0045TFFL - 45 Amp Circuit Breaker

PDG21G0045TFFL - 45 Amp Circuit Breaker

The Eaton PDG21G0045TFFL is a 45-amp, 1-pole molded case circuit breaker from the Power Defense line. Built on the Frame 2 platform, it has a 35kA interrupting rating at 277 VAC, a fixed-trip design, and load lugs. It's a straightforward choice for commercial and industrial electrical systems that require these specific ratings. The breaker measures 6 inches high, 1.38 inches wide, and 3.5 inches deep, giving it a relatively compact footprint. If you're replacing an existing breaker, the details matter. Check the PDG21G0045TFFL part number along with the amperage, voltage, pole count, interrupting rating, dimensions, and connection requirements against your existing equipment before installation.

Key Features and Benefits

• 45-amp rating for applications requiring 45A circuit protection.
• Single-pole configuration for compatible electrical systems.
• 35kA A.I.C. rating at 277 VAC for the specified voltage.
• Fixed trip keeps the configuration simple, with no field-adjustable trip setting.
• Load lugs are included.
• The Frame 2 Power Defense design provides a compact molded-case configuration.
• At only 1.38 inches wide, it takes up relatively little space in compatible equipment.
• Clearly identified electrical ratings make it easier to compare against an existing breaker or project specification.

Material Compliance and Certifications

• The PDG21G0045TFFL belongs to Eaton's globally rated Power Defense molded case circuit breaker family. The PDG2 Global platform is associated with major electrical standards, including UL 489, CSA, IEC 60947-2, and CCC, and comparable configurations are identified as RoHS compliant. Certification requirements can differ by exact model and application, so the markings and documentation for the specific breaker should always be checked when a particular certification is required.

Where It Works Best

• The breaker is intended for compatible commercial and industrial electrical distribution applications requiring a 45A, single-pole molded-case circuit breaker with a 35kA rating at 277 VAC. Depending on the equipment specifications, this can include electrical distribution equipment, panels, machinery, facility electrical systems, and breaker replacement or maintenance work.
• The Eaton PDG21G0045TFFL is particularly useful when you're matching an existing Power Defense breaker and need the same basic combination of 45 amps, one pole, fixed trip, load lugs, and 35kA at 277 VAC. Don't rely on appearance alone when choosing a replacement. Verify the part number, electrical ratings, physical dimensions, terminal arrangement, and equipment compatibility before putting the breaker into service.
