Siemens SIRIUS 3RF2 assemblies to be phased out from 1 April 2026

Siemens has announced a major change of the product status of Siemens SIRIUS 3RF2 solid-state switchgear. In total, the Siemens 3RF2 product phase-out affects 386 Siemens assemblies. P.M400 will commence on 1 April 2026.

Key facts at a glance

  • 386 Siemens SIRIUS 3RF2 assemblies are affected – making this one of the most extensive Siemens status changes in 2026.
  • The product phase-out begins on 1 April 2026 with P.M400 – the assemblies can still be ordered for the time being, but will no longer be actively marketed.
  • The subsequent status changes will follow at an unusually rapid pace – P.M410 on 1 January 2027 and P.M490 on 1 October 2027, each just nine months later.
  • This creates significant pressure on maintenance and procurement teams to act – stock levels, installation, critical systems and spare parts requirements should be reviewed at an early stage.
  • A 1:1 replacement is not automatically guaranteed – alternatives such as SIRIUS 3RF3, repair, replacement units or stockpilling must be technically assessed on a case-by-case basis.

Which SIRIUS 3RF2 assemblies are affected?

This product notice concers Siemens SIRIUS 3RF2 solid-state switching devices. Siemens lists a total of 386 affected Siemens SIRIUS 3RF2 assemblies. The Siemens 3RF2 product phase-out therefore encompasses more than just individual items. Siemens is transitioning an entire generation of devices to the successor model, the Siemens SIRIUS 3RF3.

Siemens SIRIUS 3RF2 solid-state switching devices switch electrical loads in AC networks. Many systems use Siemens SIRIUS 3RF2 solid-state switching devices for low-wear switching tasks. Typical applications include systems, resistive loads and high switching frequencies.

Siemens is replacing Siemens 3RF2 solid-state switches with Siemens SIRIUS 3RF3 solid-state switches:

  • The single-pole Siemens SIRIUS 3RF3 models were launched in October 2025

  • The 3-pole Siemens SIRIUS 3RF3 versions followed at the end of February 2026

     

The phase-out of Siemens SIRIUS 3RF2 devices will begin in early April 2026.

Legend:

  • P.M300 indicates regular supply.
  • P.M400 indicates that the product is due to be phased out.
  • P.M410 marks the start of the spare parts phase. From P.M410 onwards, new parts will no longer be available.
  • P.M490 marks the end of manufacturer availability.
  • P.M500 marks the end of the product life cycle.

Stephan Band, EICHLER GmbH

With 386 affected assemblies, the SIRIUS-3RF2 status change is one of the most extensive in 2026. The unusually tight schedule for the subsequent status change leaves maintenance and procurement with very little time to act.

Key questions regarding the end-of-life of SIRIUS 3RF assemblies

The product status change affects a total of 386 Siemens SIRIUS 3RF2 assemblies. This therefore represents a significant change to the Siemens product portfolio. Many systems may contain several variants of these Siemens assemblies. Maintenance and procurement departments should therefore check stock levels, installation locations and critical applications at an early stage. This is the only way to effectively minimise spare parts risks and unplanned breakdowns.

With the P.M400, Siemens is beginning to phase out the Siemens SIRIUS 3RF2 solid-state switchgear. For the time being, these Siemens products can still be ordered as new parts. However, Siemens is no longer actively marketing the Siemens SIRIUS 3RF2 solid-state switchgear. This gives maintenance and procurement teams time to plan. This time can be used for stock checks, migration and risk assessment.

On 1 January 2027, the Siemens SIRIUS 3RF2 will reach milestone P.M410. From this date onwards, regular orders for new units will cease. Siemens will then generally only supply Siemens SIRIUS 3RF2 semiconductor switchgear as spare parts. For critical installations, the procurement risk will increase significantly. Unplanned breakdowns can therefore lead to high costs more quickly.

On 1 October 2027, the Siemens SIRIUS 3RF2 will reach milestone P.M490. After that date, the manufacturer will no longer accept orders or supply the product. Siemens states that warranty claims are the only exception. System operators will therefore lose an important source of supply. From this date onwards, repairs, replacement and alternatives will become significantly more important.

The Siemens SIRIUS 3RF3 is the official successor to the Siemens SIRIUS 3RF2. Siemens cites more compact designs and lower power losses as advantages. Many of the changes are reflected in the new part number. Nevertheless, each system requires a technical review. The connections, power rating, design, thermal specification and approvals must be suitable for the application.

What risks does the discontinuation of the Siemens 3RF2 product pose for operators?

The discontinuation of the Siemens 3RF2 product is increasing to pressure on planning. The short timeframe leading up to P.M410 is particularly critical. There are only nine months between 1 April 2026 and 1 January 2027.

The high number of 386 affected Siemens SIRIUS 3RF2 assemblies significantly increases the complexity. Many system operators use several variants of the Siemens SIRIUS 3RF2 semiconductor switchgear in parallel. As a result, a simple individual test is often not sufficient.

Maintenance and procurement departments should systematically record all Siemens SIRIUS 3RF2 items installed. Only then can critical items be assessed. This transparency forms the basis for repairs, stock management or migration to Siemens SIRIUS 3RF3.

If this inspection is not carried out, new risks arise. Incorrect design can cause heating problems. Deviations in design may necessitate modifications. A lack of spare parts jeopardise the system's availability.

How is EICHLER supporting the phase-out of the Siemens 3RF2 product?

EICHLER supports operators of end-of-life automation technology by providing repair, maintenance and sales service. This offers additional options alongside migrations to Siemens SIRIUS 3RF3.

When it comes to maintenance, availability is paramount. EICHLER inspects and repairs Siemens SIRIUS 3RF2 solid-state switchgear. This extends the service life of existing systems, making it easier to plan for scheduled outages.

Cost-effectiveness is key when it comes to procurement. Repairs and refurbishment often reduce costs compared with refurbishment projects. Building up targeted stock levels reduces procurement pressure. At the same time, investments remain predictable.

How should maintenance personnel and operators proceed now?

The discontinuation of the Siemens 3RF2 product line calls for a clear strategy. System operators should immediately take stock of their Siemens SIRIUS 3RF2 inventory. Critical Siemens components must be prioritised. The next step is to decide between migration, repair and stockpiling.

EICHLER provides a practical solution to this. Existing Siemens SIRIUS 3RF2 technology can remain in use for longer. At the same time, the migration to Siemens SIRIUS 3RF3 remains manageable. This ensures that systems remain available, budgets stay under control and breakdowns are avoided.
