Product details

SIMATIC reversing starter with fieldbus and Class 10 protection

The Siemens 3RK1301-1DB00-1AA2 is a SIMATIC-brand reversing motor starter designed for direct-on-line reversing control of three-phase motors. This unit integrates both PROFINET and PROFIBUS DP protocols, allowing it to sit on the same fieldbus segment as the safety PLC or higher-level controller without a separate gateway. The reversing functionality is built in — no external contactor interlock required — which simplifies the wiring and reduces panel space.

Mounting is pluggable onto a terminal module, so the starter unit itself can be replaced without disturbing the main power wiring. Mounting position can be vertical or horizontal, giving flexibility in panel layout. The control supply is 24 V DC nominal, with a permissible range of 20.4 to 28.8 V DC. Maximum operating frequency is 750 operations per hour, so it is suited for moderate cycling applications like conveyor reversing stations or transfer mechanisms, but not for high-speed indexing.

Frequently asked questions

What are the key ratings for this reversing starter?

Trip Class 10 overload protection, 50 kA SCCR at 400 V, 24 V DC control supply (20.4 to 28.8 V range), PROFINET and PROFIBUS DP fieldbus, maximum 750 operations per hour, and a pollution degree of 3 at 400 V per IEC 60664.

What is the physical size of this motor starter?

The dimensions are 265 mm height, 90 mm width, and 120 mm depth. It mounts pluggably onto a terminal module in either vertical or horizontal orientation.

Does this part support reversing without external contactors?

Yes, it is a reversing starter design with built-in reversing capability. It also supports reverse starting directly, so no external contactor interlock or mechanical interlock is needed.
