It operates on a 24 VDC control supply (20.4–28.8 V range) and supports both PROFINET and PROFIBUS DP protocols. The unit is a direct starter — no reversing — and mounts pluggable onto a terminal module, fitting into a standard panel enclosure. The 7.5 kW rating at 400 V tells you the maximum motor load this starter can handle in AC-3 duty (squirrel-cage motors). The adjustable CLASS 10/10A trip class means it can be set to protect motors with different thermal time constants — CLASS 10 for standard motors, 10A for more demanding starts. The 24 VDC control supply is common in modern PLC-based panels, and the 20.4–28.8 V tolerance ensures it holds in during dips. With 2 digital inputs and 2 bytes of I/O, it integrates into a PROFINET or PROFIBUS network for remote start/stop and diagnostics. Mounts pluggable onto a terminal module — no hardwiring to the starter itself. Accepts screw-type terminals for both main energy infeed and the main current circuit. Mounting position can be vertical or horizontal, giving flexibility in tight cabinets. Vibration resistance is 2g, shock resistance 5g at 11 ms — fine for most industrial panels, but not for high-shock mobile equipment.","metaTitle":"Siemens 3RK1301-0CB20-0AA3 SIMATIC Motor Starter, 7.5 kW, 24","metaDescription":"Siemens 3RK1301-0CB20-0AA3 SIMATIC direct motor starter, 7.5 kW at 400 V, 24 VDC control, PROFINET/DP, IP20, current production.
