The S00 frame size keeps it compact at 57.5 mm tall and 72 mm deep, so it fits tight panel layouts where every millimeter counts. For AC-12 duty (resistive loads like heater banks), it handles up to 10 A maximum operating current. The magnet coil draws 3.3 W both on closing and holding, so the thermal load on the control transformer is predictable — no inrush spike to size for. ## Short-circuit coordination and wiring The 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 — and AWG equivalents from 2x 20 to 1x 12.","metaTitle":"Siemens 3RT1017-1BP42 SIRIUS S00 Power Contactor, 230 V AC C","metaDescription":"Siemens 3RT1017-1BP42 SIRIUS S00 power contactor, 230 V AC coil, 45 mm wide, IP20, screw terminals.
