Siemens SIRIUS 3RT1017-1JB41 — 24 VDC Power Contactor, Size S00
The Siemens 3RT1017-1JB41 is a SIRIUS power contactor in the compact Size S00 frame, designed for switching motor loads and resistive loads in control panels. It carries a 24 VDC coil with integrated diode surge suppression, and the coil holds at 2.3 W — the same figure for both closing and holding, so no extra power budget is needed for inrush. Rated for AC-2 duty at 5.5 kW at 400 V, and AC-4 at 8.5 A at 400 V, this contactor handles the switching of slip-ring motors (AC-2) and reversing or inching duty (AC-4) within those limits. The auxiliary contact block is rated at 10 A at 24 VDC, 6 A at 230 V, and 3 A at 400 V — enough for pilot duty on most PLC outputs or relay coils.
Mounting and Integration
Snap-on mounting onto 35 mm DIN rail per EN 50022, with screw terminals for main and auxiliary circuits. The 45 mm width and 57.5 mm height allow side-by-side mounting. Wire range for main contacts: 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), max 2x (0.75…4 mm²) solid/stranded, or AWG equivalents 2x (20…16), 2x (18…14), 1x 12. The auxiliary terminals accept the same range. IP20 on the front and at the terminals — suitable for dry indoor panels, not washdown zones.
Lifecycle and Sourcing
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. The part carries a substance prohibition date of 01.07.2006, indicating RoHS compliance from that date forward.
Fault Coordination and Environment
Type 1 coordination requires a gL/gG fuse rated 35 A; Type 2 coordination requires 20 A. Operating temperature range is -25 to +60 °C, with pollution degree 3 (conductive pollution or dry non-conductive that becomes conductive). The 72 mm depth fits standard 100 mm deep enclosures with room for wiring.
