Product Dimensions：

The 3RK1301-1JB00-0AA2 functions as a intelligent, decentralized motor starter that mounts directly onto ET 200S terminal modules. As part of the High Feature class, it offloads protection and diagnostic tasks from the central controller by executing precise current monitoring and fault handling locally. It features an integrated circuit breaker for short-circuit protection, an electronic overload release, and built-in brake control capability (24 V DC), allowing it to manage complex motor starting, stopping, and braking sequences without requiring extra external control modules. Through the ET 200S backplane interface, it continuously transmits detailed operational status, current consumption, and diagnostic messages to a central PLC over PROFIBUS or PROFINET networks.

Product Advantages

A key advantage of the 3RK1301-1JB00-0AA2 is its high level of integration, which dramatically reduces cabinet space requirements and eliminates complex discrete wiring between starters, relays, and protection devices.

The wide adjustable current range ( $2.4 \text{ A}$ to $8.0 \text{ A}$ ) paired with electronic overload protection provides higher accuracy than traditional thermal relays and reduces the number of distinct part numbers required in facility spare parts inventories.

The integrated 24 V DC brake control functionality simplifies motor drive control for applications requiring quick stopping or holding torque without requiring separate external brake control units.

Comprehensive fieldbus diagnostic capabilities allow maintenance staff to identify phase imbalances, overcurrent conditions, and trip reasons remotely, leading to significantly reduced troubleshooting time and enhanced process availability.

Its hot-swappable modular design on the ET 200S rack allows for rapid replacement during maintenance without disturbing neighboring I/O or power wiring.

Important Considerations and Precautions

When installing and commissioning the 3RK1301-1JB00-0AA2, ensure that the full-load motor current is properly set via the rotary switches or software parameters to match the motor nameplate rating, ensuring accurate electronic thermal protection.

Verify that the terminal module selected matches the electrical power supply and fieldbus configuration of the specific ET 200S station architecture.

Always isolate and disconnect power sources before inserting or removing the motor starter module to avoid electric arcing or damage to the backplane connectors.

Because the device carries an IP20 protection rating, it must be installed inside an appropriately rated enclosure (such as IP54 or NEMA 12) to protect against dust, conductive debris, and moisture ingress.

Ensure adequate clearance around the ET 200S rack for convective cooling, as high ambient temperatures combined with continuous high current loads can cause thermal derating.

Product Applications

The Siemens 3RK1301-1JB00-0AA2 is utilized across various industrial sectors where decentralized motor control and quick diagnostics are required.

Conveyor and Material Handling: Driving roller conveyors, belt drives, and sorting tables in logistics and distribution centers.
