The Siemens 3RA2814-2FW10 is an off-delay timer relay from the SIRIUS family — it holds the output closed after the control signal drops, then opens after the set time elapses. That makes it the right choice for sequenced shutdown, post-run cooling fans, or staging a contactor drop-out in a motor circuit. The adjustable time range spans 0.05 to 100 s, set via a potentiometer or DIP switches depending on the variant. Recovery time between cycles is 150 ms, so it can re-trigger quickly in a repeating sequence. Supply voltage is 24–240 V AC/DC, covering most global control voltages without needing a separate power supply module. The relay switches a maximum of 3 A; at 24 V DC the rating is 1 A, at 125 V AC it is 0.2 A, and at 250 V AC it is 0.1 A — these are the contact ratings that govern real load selection, not the headline 3 A figure.
No official successor has been announced. The part is a standard SIRIUS catalog item, so BOM continuity is stable for ongoing panel builds.
