The AC-1 resistive rating is 10 A, but the motor-duty numbers are what drive the selection. At 400 V AC-2 it handles 5.5 kW; at 400 V AC-4 it's rated 8.5 A — that's the heavy inching/plugging duty cycle. At 500 V and 690 V it still carries 5.5 kW, so it covers 400 V to 690 V three-phase motors without derating the power. The 24 V DC rating is 10 A, 60 V DC is 2 A, 110 V DC is 1 A, and 230 V DC is 0.3 A — these are the DC switching limits for resistive loads; inductive DC loads need a diode or varistor across the coil. Mechanical endurance is 30 million operations, so it's rated for high-cycle applications like conveyor diverters or packaging machinery. The contactor is 45 mm wide, 57.5 mm tall, and 72 mm deep — that's a standard Size S00 footprint that fits alongside other SIRIUS components on the same DIN rail. The screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded wire. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. The IP20 front and terminal protection means it's finger-safe once installed in an enclosure. These are the values for the main circuit; the control circuit should be fused separately per the coil rating.","metaTitle":"Siemens 3RT1017-1BF42 SIRIUS Power Contactor, 110 V DC Coil,","metaDescription":"Siemens 3RT1017-1BF42 SIRIUS power contactor, Size S00, 110 V DC coil, 45 mm wide, IP20 front, screw terminals.
