The Siemens SIRIUS 3RT2015-1BE41 is a size S00 power contactor with a 24 VDC coil and screw-type terminals. It mounts on a 35 mm DIN rail per DIN EN 60715 via screw or snap-on fastening, and its compact footprint — 45 mm wide, 58 mm tall, 73 mm deep — fits tightly packed panels where every millimeter counts. Rated for continuous operation from -25 °C to +60 °C, with storage tolerance from -55 °C to +80 °C, this contactor handles the thermal swings of an unheated enclosure or a warehouse shelf. The coil draws 10 A at 24 V rated value, with switching times of 7 to 13 ms DC and arcing time of 10 to 15 ms — fast enough for most motor and resistive load switching in control panels.
Wiring & Integration
Terminals accept solid or stranded wire: 0.5 to 4 mm² single, or 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². The screw-type connection is field-proven for panel wiring — no special tooling needed. Clearance distances: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm to the side. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward — flexible for tight enclosures or angled subpanels.
