PDG21M0040TFFL - 40 Amp Circuit Breaker

PDG21M0040TFFL - 40 Amp Circuit Breaker

When you're matching a circuit breaker to an existing system, the details matter. The Eaton PDG21M0040TFFL is a 40A, 1-pole molded case circuit breaker from the Power Defense line, built on a Frame 2 design. It has an interrupting rating of 65 kA at 277 VAC, a fixed-trip configuration, and load lugs. That combination makes it a practical choice for compatible commercial and industrial electrical systems that require dependable overcurrent protection. The breaker measures approximately 1.38 inches high, 6 inches wide, and 3.5 inches deep. For replacement work, maintenance, or a new installation, the important thing is getting the specifications right—and the PDG21M0040TFFL offers a clearly defined 40-amp rating, a single-pole configuration, and high interrupting capacity in a single molded case breaker.

Key Features and Benefits

• 40-amp rating for applications requiring 40A circuit protection.
• Single-pole design for compatible electrical systems and equipment.
• 65 kA interrupting rating at 277 VAC for applications where higher fault-current capacity is needed.
• A fixed trip keeps the protection configuration straightforward, with no field trip adjustments required.
• Load lugs are included in the specified breaker configuration.
• Power Defense Frame 2 construction provides a compact, molded-case circuit breaker solution.
• Clearly defined electrical and dimensional specifications make it easier to check compatibility before installation.

Material Compliance and Certifications

• The PDG21M0040TFFL is part of the globally rated Power Defense molded case circuit breaker family. Because certifications, listings, and material-compliance requirements can vary by exact configuration and application, always confirm the markings on the breaker and the applicable manufacturer documentation when a particular certification or compliance standard is required.

Where It Works Best

• The PDG21M0040TFFL makes sense for compatible commercial and industrial electrical applications that call for a 40A, 1-pole molded-case circuit breaker with a 65 kA rating at 277 VAC. It may be suitable for electrical distribution equipment, machinery, and control equipment, as well as for replacement applications where its ratings and physical configuration match the system requirements.
• Replacing an existing breaker? Don't rely on amperage alone. Check the PDG21M0040TFFL part number, pole count, voltage, interrupting rating, frame, dimensions, trip configuration, and lug arrangement against the breaker being replaced and the equipment requirements. A correct physical fit does not automatically mean a breaker is electrically compatible.
