The Siemens 3RT1926-2FK31 is a SIRIUS auxiliary switch with a clip-on mount. It's rated for a maximum 3 A and delivers 1 A for control-circuit loads. The adjustable time delay spans 5 to 100 s.
Clipped onto a SIRIUS contactor or base — no tools. Mounts in any position, which is a gift for tight panels where orientation is forced. Operating range -25 to +60 °C; storage -40 to +85 °C. Pollution degree 3, basic insulation. Wire: solid or stranded 18...14 AWG. Terminal accepts that range directly. Contact ratings are 1 A, 0.2 A, and 0.1 A. That's your load capacity curve — don't assume a flat 3 A across the board. Recovery time is 150 ms; minimum ON period 200 ms. If you're toggling faster than that, it won't pick up — not a general-purpose fast relay.
