Product FAQs

8 answers
What legacy Eaton breaker does the PDG23M0040TFFL directly replace?

It is a direct replacement for the obsolete Eaton and Cutler-Hammer Series C HFD3040 breaker. Upgrading to this Power Defense Frame 2 model provides the same physical footprint, bolt-on mounting, and 65kAIC rating at 480VAC.

How does the PDG23M0040TFFL differ from the TFFJ version?

The primary difference is the terminal configuration. The TFFL model includes standard lugs on the load side only, making it ideal for feed-thru panelboard mounting. The TFFJ version includes standard lugs on both the line and load sides.

Is the 40-amp trip setting on this breaker adjustable?

No. The PDG23M0040TFFL utilizes a fixed thermal and fixed magnetic (LI) trip unit. The 40A continuous current rating and instantaneous short-circuit pickup are factory-set and cannot be adjusted in the field.

Does this breaker support field-installed accessories?

Yes, Eaton Power Defense Frame 2 breakers support a modular range of field-installable internal accessories. Components like shunt trips, undervoltage releases (UVRs), and auxiliary switches can be installed securely under the front cover.

How does this breaker connect to the panelboard bus?

The PDG23M0040TFFL features a bolt-on connection type for secure mounting. Instead of snapping onto a bus stab, the line side bolts directly to the panel bus, providing a highly reliable connection suitable for high-fault commercial and industrial environments.

Can I install this breaker in older Cutler-Hammer Series C panelboards?

Yes. The Power Defense Frame 2 series shares the same physical footprint as the legacy Series C F-Frame. This allows the breaker to be backwards-compatible for seamless mounting into existing Cutler-Hammer and Eaton Series C panelboards.

Is this breaker HACR rated for HVAC equipment?

Yes, this Power Defense breaker is HACR rated. This means it is independently tested and approved to protect dedicated heating, air conditioning, and refrigeration circuits.

Does this breaker feature the Eaton Arcflash Reduction Maintenance System (ARMS)?

No. The PDG23M0040TFFL is equipped with a standard thermal-magnetic trip unit. The ARMS technology is only available on Power Defense breakers that are equipped with advanced PXR electronic trip units.
