It integrates PROFINET and PROFIBUS DP protocols for fieldbus communication, making it suitable for automated motor control in distributed I/O architectures. Its adjustable trip class (CLASS 10 and 20) means you can set the overload protection curve to match the motor's starting characteristics — CLASS 10 for faster-starting loads like pumps, CLASS 20 for higher-inertia loads like conveyors or fans. This is a key selection parameter, not a fixed rating. The unit is pluggable onto a terminal module, so it mounts without hardwiring the power circuit — the energy bus handles main power transmission. This reduces panel wiring time and simplifies replacement: pull the old starter, plug in the new one. ## Where you'd use this class of part Motor starters like this one sit in control cabinets managing individual motor loads — conveyors, agitators, fans, pumps — in automated production lines. The SIMATIC branding places it within Siemens' integrated automation ecosystem, so it communicates directly with a SIMATIC PLC over PROFINET without a gateway. The 2-byte input and output assignments mean it reports status and accepts commands over the fieldbus in a compact data frame — typical for a motor starter in a PROFINET device network. No last-time-buy or surplus-channel urgency applies here. The depth of 150 mm and height of 290 mm with a 65 mm width define its panel footprint. It mounts vertically or horizontally, which helps when fitting into existing cabinet layouts — you are not locked into one orientation. That is a high interrupting rating, typical for industrial motor starters in high-fault-current installations.","metaTitle":"Siemens SIMATIC 3RK1301-0CB10-0AA3 Motor Starter, PROFINET,","metaDescription":"Siemens SIMATIC motor starter 3RK1301-0CB10-0AA3.
