Product details

Its rated operational current at AC-12 is 10 A, and it delivers 4 kW at AC-2 / 400 V. The contactor uses spring-loaded terminals for both the main current circuit and the auxiliary/control circuit, which speeds wiring and reduces the risk of loose connections under vibration. The coil pickup voltage is 0.85 x rated value (20.4 V), and dropout is 1.1 x rated value (26.4 V). Holding power at DC is 3.3 W, so the coil stays cool in continuous duty.

Its footprint is 45 mm wide, 60 mm high, and 73 mm deep.

Switching capacity and coordination

At AC-4 (inching/plugging duty) at 400 V, the rated operational current is 8.5 A. For type of coordination 2 (no welding after a short circuit), the required backup fuse is gL/gG 20 A; for type 1 (welding permitted), use a 35 A gL/gG fuse.

Frequently asked questions

What is the closest functional second-source to the 3RT1016-2BB41?

The 3RT1015-1BB42 is a close functional peer within the same SIRIUS S00 family. Both share the 24 V DC coil and spring-loaded terminal design, but the 3RT1016-2BB41 carries a higher AC-12 rated current of 10 A versus the 3RT1015-1BB42's lower rating. Verify the motor current and duty cycle before substituting — the 3RT1016-2BB41 is the higher-rated unit and will drop into the same DIN-rail footprint without rewiring.

What is the depth of the 3RT1016-2BB41?

The depth is 73 mm, with a width of 45 mm and a height of 60 mm. This fits the standard S00 footprint for DIN-rail mounting.

What compliance documentation does Siemens provide for the 3RT1016-2BB41?

The part has a substance prohibitance date of 01.07.2006, indicating RoHS compliance per EU directive 2002/95/EC. Siemens typically provides RoHS, REACH, UL, and IEC declarations with the shipment. The IEC 81346-2 reference code is Q, which classifies it as a power switching device.
