It integrates a 24 V DC control supply, a PROFINET and PROFIBUS DP interface for fieldbus connectivity, and an adjustable overload relay with trip class 10 and 20 — so you can match the trip curve to the starting profile of pumps, fans, or conveyors without swapping hardware. The unit mounts vertically or horizontally on a terminal module, with a 150 mm depth and 65 mm width that fits standard enclosure layouts. Rated for 50 kA at 400 V, the starter handles high prospective fault currents common in industrial main distribution panels. The 24 V DC supply range spans 20.4 to 28.8 V, with a nominal 24 V, so it stays operational through moderate dips on the control bus. Pollution degree 3 at 400 V per IEC 60664 means it's rated for conductive environments typical of factory floors. ## Fieldbus integration and I/O mapping The starter carries both PROFINET and PROFIBUS DP protocol stacks on the same hardware — no option card needed. It exposes 2 bytes of input data and 2 bytes of output data over the network, giving the PLC direct readback of motor status and run/stop commands. Two digital inputs are available via the control module for local interlocks or reset buttons, but there are no onboard digital outputs; signaling back to the controller runs over the fieldbus. Vibration resistance is 2g, shock resistance 5g for 11 ms — typical for panel-mounted gear in conveyor or machine-tool applications. Power dissipation is roughly 5.67 W regardless of bypass state, so thermal management in a dense enclosure is straightforward.","metaTitle":"Siemens 3RK1301-0BB10-0AA4 SIMATIC Motor Starter, 24 V DC, P","metaDescription":"Siemens 3RK1301-0BB10-0AA4 SIMATIC motor starter with adjustable trip class 10/20, 24 V DC, PROFINET/PROFIBUS DP.
