For DC switching at the coil rated voltage, the contactor is rated 1 A at 110 V, 0.3 A at 220 V. On the AC side for motor loads, it delivers 5.5 kW at 400 V under AC-2 duty and 8.5 A at 400 V under AC-4 duty. The main circuit screw terminals accept 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or max 2x (0.75…4 mm²) solid/stranded, with AWG equivalents 2x (20…16), 2x (18…14), 1x 12. The auxiliary and control circuit terminals are also screw-type. ## Sourcing posture This is a current-production Siemens SIRIUS contactor, sourced through independent distribution channels.","metaTitle":"Siemens 3RT1017-1KF42-0LA0 SIRIUS Power Contactor, 110 V Coi","metaDescription":"Siemens SIRIUS 3RT1017-1KF42-0LA0 power contactor, Size S00, 110 V coil with varistor, screw terminals, DIN rail mount.
