The Siemens SIRIUS 3RT2017-2KB41-1AA0 is a size S00 coupling contactor with a 24 VDC coil and spring-type terminals. It is designed for switching DC loads in control circuits, with a 10 A rating at 24 V and derated values for higher voltages: 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 coil holds at 24 V nominal, with a pick-up threshold of 0.7 × rated value.
Mounting and Integration
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, in a standing position on a horizontal surface. Dimensions are 45 mm wide, 70 mm high, and 73 mm deep — fits standard S00 footprint in a control panel. Spring-type terminals accept 0.5 to 4 mm² solid or stranded wire, including 2 × (0.5 to 4 mm²) for paralleled connections. Clearance: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the sides.
