Raritan PX3 end of life: dates, affected part numbers and PX4 replacements
Raritan PX3 End of Life: Key Dates and Replacement Guide
Data centre operators relying on Raritan PX3 power distribution units need to plan their infrastructure upgrades now. Legrand’s announcement of end-of-life dates for select PX3 models means organisations must understand the timeline and secure replacements before support ends.
The PX3 series—including the 1000, 4000, and 5000 rack PDUs, 3000 inline meters, and rack transfer switches—delivers critical power monitoring and distribution across demanding data centre environments. With the last order date set for December 2026 and service ending December 2028, this guide covers affected part numbers and how to transition to the newer PX4 platform.
Raritan PX3 end of life: dates, affected part numbers and PX4 replacements
Legrand announced end of life for select Raritan PX3 rack PDUs, inline meters and rack transfer switches on 1 June 2026. The last order date is 1 December 2026. Service ends on 1 December 2028.
Five lines are affected: the PX3 1000, 4000 and 5000 series rack PDUs, the PX3 3000 series inline meters, and the PX3 rack transfer switches. The announcement covers 433 part numbers: 318 rack PDUs, 46 inline meters and 69 transfer switches. It names select part numbers only, so not every PX3 in your racks is on the list.
If you run PX3 units, or keep spares you top up, this is a matching exercise with a deadline. Raritan publishes every affected part number, and for 157 of them it names the PX4 that replaces it.
What end of life means for a rack PDU
End of life is a sequence of dated milestones, not a single event. End of sale, or last order date, is the final date to buy the product or add it to a support contract. End of new contract renewal is the final date to order or extend a service or warranty contract. End of service life is the final date to receive service, and the last date that bug fixes and security updates are provided.
The product does not stop working on any of these dates. What changes is who is obliged to support it, and for how long. Raritan’s policy describes a typical timeline of six months from announcement to last order, and three years to end of service life.
Three PX3 waves, three sets of dates
Raritan announced select PX3 end of life in July 2025, December 2025 and June 2026. The dates differ by wave, and a part number sits in one of them. The earlier waves are listed on the same Raritan page and in the same master parts list, so a full audit covers all three.

Where Raritan names a replacement, and where it does not
Raritan names a PX4 for 150 of the 318 rack PDUs and for 7 of the 46 inline meters. That is 157 of 433. The mapped replacements keep the metering level of the original: PX3 1000 series parts map to input-metered PX4 models, 4000 series to outlet-metered, and 5000 series to outlet-metered and switched.
One example. The PX3-1075R maps to the PX4-1256CR-C8E8A0: single phase, 100 to 240 V, 20 A, 12 outlets made up of 8 x C13 and 4 x HDOT Cx, input metered, 1U horizontal, SecureLock ready, with a high-resolution LCD display, the iX controller, USB-A, USB-B and sensor connections.
Named PX4 replacement
- 150 rack PDUs and 7 inline meters
- Same metering level as the original
- Check plug, voltage and outlet mix before you accept it
Contact Raritan
- 168 rack PDUs and 39 inline meters
- All 69 rack transfer switches
- No direct replacement listed, so the answer depends on the rack
The 276 with no named replacement are not abandoned. Raritan’s announcements say its team will help find an alternative or comparable product, and that a direct replacement is often available. It simply needs a person to look at what the rack draws, how it is fed and what monitors it.
How to audit your estate before 1 December
Start with the model numbers on the front of each unit and a quantity for each. Match them against the master parts list, which Raritan last updated on 10 June 2026. Mark each as mapped, unmapped or not listed.
For mapped parts, check the input plug and voltage, the outlet mix, and whether the metering level matches how you use the unit. Check what depends on the old unit as well, such as DCIM, monitoring and scripts that poll it. For unmapped parts, ask for a recommendation now rather than after the last order date. For the parts you plan to keep running, decide whether you need spares and whether you want service coverage in place until 2028.
Raritan’s policy is clear that you can keep using a product after end of life. The risk is coverage, not function. After end of service life there is no standing commitment to bug fixes or security updates.
Frequently asked questions
Which Raritan PX3 products are end of life?
Select part numbers in five lines: the PX3 1000, 4000 and 5000 series rack PDUs, the PX3 3000 series inline meters and the PX3 rack transfer switches. Legrand announced the June 2026 wave on 1 June 2026. It covers 433 part numbers: 318 rack PDUs, 46 inline meters and 69 rack transfer switches. Not every PX3 is on the list, so check each model number against Raritan’s master parts list.
What are the key dates for the June 2026 PX3 announcement?
The announcement date is 1 June 2026. The last order date and the end of new contract renewal date are both 1 December 2026. End of service life is 1 December 2028. Raritan describes end of service life as the last date to receive service under a contract or warranty, and the last date that bug fixes and security updates are provided.
Can I keep using a PX3 after end of life?
Yes. Raritan’s end-of-life policy says so. Units under a valid service contract stay supported until the contract expires. After end of service life there is no further service, bug fix or security update as a rule, although the policy says firmware updates may be provided for a limited time to address critical bugs or vulnerabilities. Raritan warns that ignoring an announcement can leave you without coverage for security vulnerabilities and for incompatibilities with newer accessories.
What replaces the PX3?
For 157 of the 433 part numbers in the June 2026 wave, Raritan names a PX4 replacement: 150 rack PDUs and 7 inline meters. For example, the PX3-1075R maps to the PX4-1256CR-C8E8A0. For the other 276 part numbers, which include all 69 transfer switches, Raritan lists no direct replacement and asks customers to contact them.
Were there earlier PX3 end-of-life announcements?
Yes. Raritan announced select PX3 end of life in July 2025 and December 2025 as well. Parts in the July 2025 wave reached their last order date on 31 December 2025 and service ends on 30 December 2027. Parts in the December 2025 wave reached their last order date on 15 June 2026 and service ends on 15 June 2028. These are the latest dates for those parts on Raritan’s master list, so confirm each part number.
What should I do before 1 December 2026?
Make a list of the PX3 PDUs, inline meters and transfer switches in your racks, with model numbers and quantities. Match them against Raritan’s master list. Decide how many units you need to buy before the last order date, and how many to replace. For named PX4 replacements, check the input plug, voltage, outlet mix and metering level. For parts with no named replacement, ask your Raritan partner for a recommendation before the last order date passes.
