Eaton PDG4XPXR30800B2N — 800A Power Defense PXR10 LSI Trip Unit

Eaton PDG4XPXR30800B2N: 800A PXR10 LSI Power Defense Trip Unit

If you're upgrading or replacing the electronic release on a Power Defense Frame 4 breaker, the Eaton PDG4XPXR30800B2N is the part you're looking for. This is the PXR10 trip unit rated at 800A, three-pole, with LSI protection — the intelligent core that determines how a PD4 Global breaker senses and responds to overcurrent and short-circuit conditions. It is the trip unit only; it mounts into a compatible Power Defense Frame 4 breaker.

We work with Power Defense components every day, so here's what actually matters about this release: the PXR10 platform gives you adjustable Long-time, Short-time, and Instantaneous protection bands, letting you tune coordination to your system rather than relying on fixed thermal-magnetic curves. That adjustability is the whole reason to spec an electronic trip unit over a legacy molded-case device.

Where This Trip Unit Fits

The PDG4XPXR30800B2N belongs in 800A-class Power Defense Frame 4 applications: switchgear and switchboards, large motor and feeder protection, data center distribution, and industrial plants where selective coordination matters. Because Eaton designed the PXR releases to be field-installable, you can build, repair, or upgrade a breaker's protection package without scrapping the frame.

Frequently Asked Questions

Is the PDG4XPXR30800B2N a breaker or a trip unit?

It is a trip unit — specifically the PXR10 electronic release. It is not a complete breaker and must be installed into a compatible Power Defense Frame 4 (PD4) breaker.

What protection does the PXR10 LSI provide?

LSI stands for Long-time, Short-time, and Instantaneous protection. Each band is adjustable, allowing precise overcurrent and short-circuit coordination. It does not include integral ground-fault (the "G" in LSIG) protection.

What breakers accept this trip unit?

It is designed for Eaton Power Defense Frame 4 molded case circuit breakers (Frame J-K, PD4 Global) rated up to 800A. Confirm the host breaker frame and rating before installation.

What is the difference between PXR10 and higher PXR units?

The PXR10 is Eaton's foundational electronic release, focused on adjustable LSI protection. Higher-tier releases such as PXR20 and PXR25 add metering, waveform capture, and communications. If you need protection without integral metering, the PXR10 is the right choice.

What standards is it certified to?

The unit is listed to UL 489, CSA, and IEC 60947-2, carries the CCC mark, and is RoHS compliant — making it suitable for both North American and global installations.

Can I field-install this myself?

Eaton designed PXR releases to be field-installable by qualified personnel. Installation should always follow Eaton's instructions and be performed by a licensed electrician on a de-energized breaker.
