The Siemens SIMATIC 3RK1301-0DB00-0AA2 is a direct-starter motor starter with CLASS 10 overload protection, designed for 24 V DC control supply. It supports both PROFINET and PROFIBUS DP fieldbus protocols, making it a drop-in networked motor starter for SIMATIC-based panels. Rated short-circuit current 50 kA at 400 V — that means it can be installed on a high-fault bus without upstream fusing coordination headaches, as long as the feeder breaker is sized accordingly.
Plugs onto a terminal module — no hardwiring of the base unit. Mounting position vertical or horizontal. Dimensions 120 mm deep, 45 mm wide, 265 mm tall — fits standard 45 mm wide DIN-rail footprint. Shock rated 5g / 11 ms, vibration 2g. Pollution degree 3 at 400 V, 2 at 500 V per IEC 60664.
