It carries a 24 VDC coil with a pick-up threshold of 0.85 x rated voltage and a drop-out of 1.85 x rated voltage, so the coil holds reliably at nominal and drops out cleanly when the control signal falls. The main contacts are rated for 10 A at 24 VDC, 2 A at 48 VDC, 2 A at 60 VDC, 1 A at 110 VDC, 0.9 A at 125 VDC, 0.3 A at 220 VDC, and 3 A at 400 VDC — these are the DC-13 switching capacities, meaning the contactor can break inductive DC loads at those currents. For AC motor duty, it is rated 0.75 hp at 230 V. The mechanical service life is typically 30,000,000 operations. Maximum switching rates vary by duty: 1,000 cycles/hour for AC-1 (resistive), 750 cycles/hour for AC-2 and AC-3 (motor starting), 250 cycles/hour for AC-4 (plugging/inching), and 750 cycles/hour for AC-3e.","metaTitle":"Siemens 3RT2015-1VB41 SIRIUS coupling contactor, 24 VDC coil","metaDescription":"Siemens 3RT2015-1VB41 SIRIUS coupling contactor, 24 VDC coil, Size S00, 10 A at 24 VDC, screw terminals, current production.
