Product details

The lifecycle stage is marked 'current', meaning Siemens continues to manufacture the 3RT2035-1AK64 and supports it as an active catalog item. For a critical-spare buyer covering legacy installs, this removes the urgency of a last-time buy or surplus hunt.

Integration Notes

For panel retrofits, the 10 mm upward clearance allows cooling airflow; maintain the 6 mm side gap to adjacent devices. No built-in auxiliary contact block is included (: Auxiliary Switch: No). If the application requires early warning or status feedback, order a separate auxiliary switch module compatible with the S2 frame.
