Screw-type terminals on the coil accept solid or stranded wire from 0.5 to 4 mm² (single) or 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², and 2x 4 mm² for paralleled conductors. The auxiliary switch is rated for 10 A at 24 V, 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 — covering pilot-duty and PLC-level signals across common control voltages. ## Switching Frequency and Operating Conditions Maximum switching rate depends on duty: 1,000 cycles per hour at AC-1 (resistive), 750 cycles per hour at AC-2 and AC-3 (motor starting/running), 750 at AC-3e, and 250 at AC-4 (plugging/inching).","metaTitle":"Siemens 3RT2017-1BF42 SIRIUS Power Contactor, 110 V Coil, Si","metaDescription":"Siemens SIRIUS 3RT2017-1BF42 power contactor, Size S00, 110 V AC coil, screw terminals, 45 mm wide.
