Its AC-3 motor rating reaches 5.5 kW at both 500 V and 690 V, meaning it can handle 3-phase induction motors up to that power at those line voltages. The AC-4 reversing/inching rating is 8.5 A at 400 V, which governs frequent jogging or plugging duty cycles. The operating range is 0.85 to 1.1 times the rated voltage, which for a 24 VDC coil means it picks up at about 20.4 V and holds through 26.4 V.
The 45 mm width and 57.5 mm height fit standard S00 panel layouts; depth is 72 mm, which clears most shallow enclosures. The front face carries IP20 finger-safe protection; the terminals are also rated IP20. The mechanical endurance is 30 million operations typical, so it outlasts most machinery lifecycles in normal switching service.
Wiring and protection
Screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid or stranded conductors. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. Strip length and torque follow standard Siemens S00 practice. Type 2 coordination requires 20 A. The contactor carries one normally open instantaneous auxiliary contact for feedback or interlocking.
For a BOM freeze or panel design, the 3RT1017-1BW41 is a stable order code with consistent terminal numbering and macro support across the SIRIUS platform.
