PDG3XPXR30600B2N Eaton Power Defense PXR10 LSI Trip Unit – 600A, 3-Pole, Frame 3

PDG3XPXR30600B2N Eaton Power Defense PXR10 LSI Trip Unit – 600A, 3-Pole, Frame 3

If you've traced a problem to your Eaton Power Defense breaker and found it's the trip unit you need—not the entire breaker—the PDG3XPXR30600B2N is the right part. The trip unit is the electronic "brain" that decides when the breaker opens on an overload or fault. This is the PXR10 LSI version: a 600-amp, three-pole module that fits Eaton Power Defense Frame 3 (PD3 Global, J–K frame) breakers.

"LSI" simply means it adjusts three things—how it responds to a sustained overload (long delay), a short circuit (short delay), and a hard fault (instantaneous). You can set it on the front of the unit with its rotary switches, or use Eaton PXPM software for finer control. It carries UL 489, CSA, and IEC certifications, so you can order knowing it's the correct, code-listed replacement.

Common Applications

• Replacing the trip unit in an Eaton Power Defense Frame 3 breaker instead of the whole breaker
• Setting up 600 A overload and short-circuit protection on a Frame 3 breaker
• Maintenance and repair of commercial or facility electrical distribution panels
• Getting a breaker back in service when the trip unit is the part that failed

FAQ

Is this a circuit breaker?
No—it's the trip unit that goes inside an Eaton Power Defense Frame 3 breaker. If you need the complete breaker, this isn't it, but if your breaker just needs a new trip unit, this is the part.

How do I know if it fits my breaker?
It works with Eaton Power Defense Frame 3 (PD3 Global, J–K) breakers rated up to 600 A. Check that your breaker is a Frame 3 model before ordering.

What does "PXR10 LSI" mean?
PXR10 is Eaton's value electronic trip unit, and LSI means it has adjustable Long-delay, Short-delay, and Instantaneous protection settings.

Do I need a computer to use it?
Not for basic setup—you can adjust it with the switches on the front. Software (Eaton PXPM, via USB) is only needed for advanced settings.

Is it safe and certified?
Yes. It's listed to UL 489 and IEC 60947-2, CSA certified, CCC marked, and RoHS compliant.
