SIEMENS 3RK1301-0CB20-0A84 Direct Soft Starter

Product Dimensions：

The Siemens 3RK1301-0CB20-0A84 is a high-performance Electronic Direct Starter from the SIRIUS M200D family. It is a motor starter specifically designed for distributed installations, meaning it is mounted directly on the machine or conveyor rail rather than inside a central control cabinet.

Product Detailed Description

The 3RK1301-0CB20-0A84 is a PROFINET-based motor starter. It is housed in a rugged, high-protection enclosure (IP65) and is used to switch and protect three-phase motors. This specific model features an electronic switching mechanism (as opposed to mechanical contactors), which allows for a much higher switching frequency and a significantly longer service life.

Technical Parameters

Product Advantages

• Decentralized Efficiency: By installing the starter close to the motor, you drastically reduce the length of expensive motor cables and simplify the overall wiring architecture.
• PROFINET Integration: Features an integrated switch for easy “daisy-chain” networking, providing extensive diagnostic data back to the PLC (e.g., current values, error messages, and maintenance timers).
• Wear-Free Switching: The electronic switching technology is ideal for high-cycle applications where standard mechanical contactors would wear out too quickly.
• Full Motor Protection: Includes electronic overload protection and thermistor motor protection to ensure the motor is shielded from overheating and phase failures.
• Modular Design: The starter consists of a communication module and a power module, allowing for easy replacement or upgrades without re-wiring the entire bus.

Important Considerations (Precautions)

• Current Setting: Ensure the “Current Setting” (I_e) on the device or via software matches the rated current on the motor’s nameplate. Improper settings will lead to nuisance tripping or motor damage.
• M12 Connectors: This unit uses M12 and ISO 23570 connectors. Ensure you use the correct shielded cables to maintain the IP65 rating and prevent electromagnetic interference (EMI).
• Brake Voltage: Verify that the mechanical brake on your motor is compatible with the 400 V AC output provided by this starter; using a 24 V DC brake with this model without a transformer will cause damage.
• Mounting Orientation: For optimal heat dissipation, follow the recommended mounting orientation specified in the manual.

Product Applications

The 3RK1301-0CB20-0A84 is widely used in automated logistics and large-scale manufacturing:

• Conveyor Systems: Ideal for airport baggage handling, distribution centers, and parcel sorting where hundreds of motors are spread over a large area.
• Automotive Assembly: Controlling small motors on assembly lines that require high-speed communication and frequent switching.
• Packaging Machinery: Providing precise control for rollers, feeders, and small auxiliary motors.
• Food & Beverage: Used in bottling lines and wash-down areas thanks to its robust IP65 protection.
