Reversing starter with PROFINET and PROFIBUS DP
The 3RK1301-0JB00-1AA2 is a SIMATIC motor starter configured as a reversing starter — it controls motor direction forward and reverse without external contactors. It supports both PROFINET and PROFIBUS DP protocols, so it drops into either fieldbus architecture without a gateway. Rated short-circuit current is 50 kA at 400 V, giving the panel builder headroom for high-fault installations without cascading upstream breakers.
Panel fit and supply voltage tolerance
Dimensions are 120 mm deep, 90 mm wide, 265 mm tall — fits standard control-panel backplanes. Mounting position is vertical or horizontal, with pluggable attachment onto a terminal module for quick swap without rewiring the field cables. Vibration resistance is 2g, shock resistance 5g / 11 ms — rated for machine-mounted cabinets.
