SIRIUS 3RT2017-2BB41 — Panel Fit and Coil Specs
The Siemens SIRIUS 3RT2017-2BB41 is a Size S00 power contactor with a 24 VDC coil, rated to pull in at 0.8 of nominal and hold at 1.1 times the rated value. The spring-type terminals accept 0.5 to 4 mm² solid or stranded wire, and the contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. Dimensions are 45 mm wide, 70 mm high, and 73 mm deep — a compact footprint that fits standard panel layouts.
Mounting position is flexible: the contactor allows ±180° rotation on a vertical surface and can be tilted forward or backward by ±22.5°. Minimum clearances to adjacent parts are 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side — plan your DIN-rail spacing accordingly to avoid derating or heat buildup.
