It's built as a reversing starter, meaning it contains two contactors mechanically interlocked so only one can close at a time, preventing a phase-to-phase short when reversing direction. It's designed to plug onto a terminal module, so the power wiring stays in the panel while the control module can be swapped without disturbing the main circuit. The unit measures 265 mm high by 90 mm wide by 120 mm deep, which fits a standard 90 mm DIN-rail footprint. It's rated for vertical or horizontal mounting, giving flexibility in cabinet layout. The short-circuit breaking capacity is 50 kA at 400 V. For a panel builder, this sets the SCCR (short-circuit current rating) of the branch circuit — you need upstream protection (fuse or breaker) rated to limit let-through to 50 kA or less. This is a strong rating, suitable for industrial mains with high fault capacity. Supply voltage is 24 V DC nominal, with a permissible range of 20.4 to 28.8 V. The coil holds reliably at 24 V; if your control supply dips below 20.4 V during a brownout, the starter drops out. The maximum operating frequency is 750 cycles per hour — that's about one start every 4.8 seconds, which covers most reversing duty cycles but not high-speed jogging. The unit supports PROFINET and PROFIBUS DP protocols, so it can be integrated into a Siemens S7 automation network directly. The I/O assignment is 1 byte each for inputs and outputs, which maps to a small data block in the PLC for control and status. There are no onboard digital I/O points — all control signals come over the fieldbus. The product brand is SIMATIC, which is Siemens' automation platform. The pollution degree rating is 3 at 400 V and 2 at 500 V per IEC 60664 / IEC 61131 — this means it's suitable for industrial environments with conductive dust or occasional condensation, but not for wet or corrosive atmospheres without additional enclosure protection.","metaTitle":"SIMATIC 3RK1301-1CB00-1AA2 reversing starter, CLASS 10, PROF","metaDescription":"SIMATIC 3RK1301-1CB00-1AA2 reversing motor starter, 24 V DC, CLASS 10, 50 kA SCCR at 400 V, PROFINET, current production.
