The Siemens SIRIUS 3RT2016-2FB41-1AA0 is a size S00 power contactor with a 24 VDC coil, terminated via spring-type terminals. It occupies a 45 mm wide DIN-rail footprint and is rated for screw and snap-on mounting onto 35 mm DIN rail per DIN EN 60715, standing on a horizontal mounting surface. The auxiliary switch is included on the unit.
Ratings and duty cycles
The auxiliary contact switching capacity varies by voltage: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The arcing time is 10 to 15 ms, and the DC dropout time spans 38 to 65 ms. Maximum switching frequency depends on duty: 1,000 operations per hour at AC-1, 750/h at AC-2 and AC-3, and 250/h at AC-4.
Termination and clearances
Spring-type terminals accept solid or stranded conductors from 0.5 to 4 mm², including two conductors per clamp (2x 0.5 to 4 mm²). Minimum clearance distances: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm to the side. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C.
