The 3RT2015-2BB41-ZW97: The 24 VDC coil draws its rated current at 24 V and drops out reliably below the undervoltage threshold — typical for SIRIUS contactors, the pick-up voltage is around 0.8 x rated (19.2 V) and dropout below about 0.55 x rated (13.2 V). The 10 A rating at 24 VDC covers the main contact switching for resistive and moderate inductive DC loads; for motor duty (AC-3), derate to the motor full-load current the contactor is listed for. The size S00 frame keeps the footprint compact at 45 mm wide, 70 mm tall, and 73 mm deep — fits standard 45 mm DIN-rail spacing with 10 mm clearance above and below, 6 mm at the sides.

Frequently asked questions
What are the key dimensions of 3RT2015-2BB41-ZW97?
Width 45 mm, height 70 mm, depth 73 mm. Clearance: 10 mm above, below, and forwards; 6 mm at the sides.
Will 3RT2015-2BB41-ZW97 drop into a panel specified for 3RT2015-2BB44-3MA0?
Both are size S00 Siemens SIRIUS contactors with the same mounting footprint and DIN-rail latch, so mechanical fit is identical. The difference is the coil voltage: 3RT2015-2BB41-ZW97 uses 24 VDC, while 3RT2015-2BB44-3MA0 uses a different coil voltage (check the specific variant). Verify coil compatibility before substitution.
