The 3RT6016-1BW41 is a Siemens SIRIUS size S00 power contactor with a 48 V DC coil, rated for switching three-phase motors up to 13 kW at 400 V AC-3 (the standard motor-duty category per IEC 60947-4-1). The 48 V DC coil draws 6 A at 24 V and 1 A at 110 V, so the control transformer or DC supply must be sized for the inrush, not just the hold-in current. The S00 frame is 45 mm wide, 57.5 mm tall, 73 mm deep.
AC-3 motor power and switching frequency
At AC-3 duty the contactor is rated for 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V — all at 60 °C ambient. The maximum switching rate at AC-3 is 750 operations per hour, which covers most pump, fan, and conveyor cycling. For resistive loads (AC-1) the rate climbs to 1 000 1/h, and for DC switching the coil circuit handles up to 10 000 1/h.
RoHS compliance date is May 1, 2012, so it meets current EU substance restrictions.
