It integrates PROFINET and PROFIBUS DP protocols, making it a networked component for distributed motor control in automation cells. The adjustable trip class (CLASS 10 and 10A) means it can be set to protect motor overloads with a faster or standard thermal curve — CLASS 10A is tighter for submersible or high-inertia loads where rapid trip is needed, while CLASS 10 covers standard induction motors. The 50 kA rated short-circuit current at 400 V gives substantial fault-clearing capacity without upstream fuses needing to coordinate down to a lower let-through. Mounts vertically or horizontally, pluggable onto a terminal module. Dimensions: 290 mm height, 65 mm width, 150 mm depth. Operates at 0 to 60 °C ambient, storage and transport range -40 to +70 °C. Shock rated 5g / 11 ms, vibration 2g. Pollution degree 3 at 400 V, 2 at 500 V per IEC 60664 / IEC 61131 — suitable for industrial control panels with moderate conductive dust or humidity. Provides 2 bytes of inputs and 2 bytes of outputs. Two digital inputs are available via the control module. No onboard digital outputs for brake control.","metaTitle":"Siemens SIMATIC 3RK1301-0BB20-0AB4 Motor Starter, 24 V DC, 5","metaDescription":"Siemens SIMATIC 3RK1301-0BB20-0AB4 direct motor starter. 24 V DC supply, CLASS 10/10A adjustable trip, 50 kA SCCR at 400 V.
