Eaton / Cutler-Hammer PDG23M0030TFFL Molded Case Circuit Breaker

In the Eaton Power Defense nomenclature, "PDG" stands for Power Defense Globally Rated. The "2" indicates a Frame 2 size, and "3" specifies 3 poles. The "M" denotes a medium interrupting rating of 65kAIC at 480VAC. The "0030" indicates a 30-amp rating, and "TFF" signifies a fixed thermal and fixed magnetic trip unit. Finally, the "L" means the breaker is supplied with standard load-side lugs.

This Power Defense Frame 2 breaker serves as a modern drop-in replacement for older 30-amp Eaton Series C (HFD3030) and Series G (EGH3030) molded case circuit breakers. It will mount directly into standard Eaton panelboards configured for those legacy frame sizes.

The "L" suffix in the catalog number indicates that this breaker ships with standard aluminum or copper lugs installed on the load side. Since it is a bolt-on panelboard breaker, the line side fastens directly to the bus, while the load lugs securely accept 14 AWG to 1/0 AWG conductors.

No. The PDG23M0030TFFL features a fixed thermal and fixed magnetic (TFF) trip unit. It provides standard, non-adjustable overcurrent and short-circuit protection at its 30-amp rating, so no field calibration is required.

Yes. Eaton Power Defense Frame 2 complete circuit breakers are fully reverse-feed capable under UL guidelines. This allows you to safely route power in either direction, offering flexibility when wiring line and load connections in your enclosure.

Yes, the thermal-magnetic trip unit allows the PDG23M0030TFFL to safely protect direct current circuits. It carries a designated DC interrupting rating of 22kAIC at 250VDC for use in solar, battery, or industrial DC applications.

Yes, as a modern UL 489 listed molded case circuit breaker, the PDG23M0030TFFL is inherently HACR rated. It is fully approved for protecting motor group applications found in commercial HVAC and refrigeration equipment.

The trip unit uses two distinct methods to ensure electrical safety: a thermal bi-metal element that responds to prolonged overloads by slowly heating up and tripping the circuit, and a magnetic coil that reacts instantaneously to clear high-level short-circuit faults.
