The 3RT2035-1AK64: Mounting is via screw and snap-on onto 35 mm DIN rail per DIN EN 60715. Clearances: 10 mm upward, 10 mm downward, 10 mm forward, and 6 mm to the side. Operating temperature range is -25 to +60 °C; storage range extends to -55 to +80 °C.
Sourcing and Lifecycle
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
The 3RT2035-1AK64 occupies 55 mm width on the DIN rail and requires 174 mm depth from the mounting surface — enough to clear terminal wiring and arc chutes. 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.
