For DC switching, the contactor is rated 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. These are the actual interrupting currents for DC loads—important when sizing for solenoid or brake circuits where DC arcing behavior differs from AC. Maximum switching frequency varies by duty: 1,000 cycles/hour for AC-1 resistive loads, 750 cycles/hour for AC-2 and AC-3 motor starting, 750 cycles/hour for AC-3e, and 250 cycles/hour for AC-4 inching/plugging. These limits reflect thermal buildup in the arc chamber—exceeding them shortens contact life. For dual-wire terminations, it accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². The main contacts also accept AWG 20 to 12. An auxiliary switch is included as standard, which saves adding a separate block for basic status feedback.","metaTitle":"Siemens 3RT2017-1BB42-1AA0 SIRIUS S00 Power Contactor, 24 VD","metaDescription":"Siemens SIRIUS 3RT2017-1BB42-1AA0 power contactor, size S00, 24 VDC coil, 10 A at 24 VDC, screw terminals, DIN rail mount.
