It accepts a 24 V DC control supply (20.4 to 28.8 V DC) and communicates over both PROFINET and PROFIBUS DP, so it fits into either a Siemens S7 or third-party PLC network without a gateway. For a panel fed from a transformer with 50 kA available fault current, this starter coordinates without an upstream current-limiting fuse. The degree of pollution is rated 3 at 400 V and 2 at 500 V per IEC 60664 / IEC 61131, so it's suited for industrial environments with conductive dust or occasional condensation, but not for clean-room or medical-grade air. It's a reversing starter, so it has built-in interlocking for forward/reverse — no external contactor pair or mechanical interlock kit needed. Direct start is not supported; this module is designed for reversing duty only. The two digital inputs (2 byte input and output assignment) handle start/stop and direction commands from the PLC. Mounting is pluggable onto a terminal module — no DIN-rail clips. The main energy infeed uses screw-type terminals, and the main energy transmission goes via an energy bus (daisy-chain power distribution between modules). That means you need the matching terminal module and bus connector; it's not a standalone DIN-rail mount. ## Where it goes in a panel This starter is sized for a control cabinet: 290 mm high, 130 mm wide, 150 mm deep. It mounts vertically or horizontally, so it fits in shallow enclosures or tight sub-panels. Shock resistance is 5g for 11 ms, vibration resistance 2g — typical for machine-mounted cabinets on conveyors or presses, not for high-shock applications like forging hammers. That's a standard industrial range — fine for unheated warehouses, but not for freezer or oven environments.","metaTitle":"Siemens SIMATIC 3RK1301-0BB10-1AA3 Motor Starter, CLASS 10","metaDescription":"Siemens SIMATIC 3RK1301-0BB10-1AA3 reversing motor starter, CLASS 10, 24 V DC, PROFINET & PROFIBUS DP, 50 kA SCCR at 400 V.
