PDG23M0045TFFJ - 45 Amp Circuit Breaker

PDG23M0045TFFJ - 45 Amp Circuit Breaker

The Eaton PDG23M0045TFFJ is a 45-amp, 3-pole molded-case circuit breaker from the Power Defense line. Built on the Frame 2 platform, it has a 65 kA interrupting rating at 480 VAC, providing the fault-current capability needed for many commercial and industrial electrical applications. This breaker uses a fixed-trip design and comes with line and load lugs, so there aren't adjustable trip settings to configure. It's a straightforward setup for applications that call for these specific ratings. If you're replacing an existing breaker, the details matter: amperage and pole count are only part of the match. Check the full PDG23M0045TFFJ part number along with the frame, trip type, interrupting rating, lug configuration, and physical size before installation.

Key Features and Benefits

• 45-amp rating for compatible 45A circuits and equipment
• 3-pole configuration for applicable three-phase systems
• 65kA at 480 VAC A.I.C. rating for applications requiring higher short-circuit interrupting capacity
• Power Defense Frame 2 molded case design
• Fixed trip provides predetermined protection without adjustable trip settings
• Line and load lugs provide connection points on both sides of the breaker
• Clearly defined ratings make it easier to compare against an existing breaker or equipment requirements

Material Compliance and Certifications

• The PDG23M0045TFFJ is part of Eaton's globally rated Power Defense molded case circuit breaker family. Compliance requirements can depend on the exact breaker configuration and the equipment in which it's being installed. For that reason, certifications, approvals, and material-compliance requirements should be verified using the markings on the breaker and the applicable manufacturer documentation before installation.

Where It Works Best

• This breaker is a sensible choice when the electrical system specifically calls for a 45A, 3-pole MCCB with a 65kA rating at 480 VAC. Typical uses may include compatible commercial or industrial distribution equipment, feeder circuits, machinery, control equipment, and other three-phase electrical applications.
  
• The 65 kA interrupting rating is an important consideration in systems where the available fault current exceeds what a lower-AIC breaker can safely interrupt. The fixed-trip configuration also keeps things simple when adjustable protection settings aren't needed.
