Siemens 3RK1301-1DB00-0AA2 DOL Motor Starter Module

Description

Siemens 3RK1301-1DB00-0AA2 DOL Motor Starter Module

Product Dimensions：

The Siemens 3RK1301-1DB00-0AA2 is an electromechanical Direct-On-Line (DOL) Motor Starter Module (designated as the DS1-X) belonging to the legacy SIMATIC ET 200S distributed I/O system family. It provides an efficient and highly integrated solution for starting and protecting small low-voltage AC three-phase motors.

Lifecycle Note: This product has been officially phased out/discontinued by Siemens. Its modern functional successor is the SIMATIC ET 200SP motor starter system.

Technical Parameters

Key Product Advantages

• Space-Saving Modular Design: As part of the modular ET 200S station, it plugs straight onto a terminal module block, eliminating tedious traditional control circuit wiring and drastically reducing cabinet space.
• Integrated Diagnosis: Provides basic on-site LED status indicators (such as Group Fault and Device State), simplifying loop check-outs and system troubleshooting.
• High Short-Circuit Strength: Features a 50 kA breaking capacity, ensuring Type 2 coordination parameters are met safely within busy industrial grids.
• Expandable Brake Control: The hardware architecture allows a plug-in extension module to be attached natively if mechanical motor brake control is required for the application.

Important Considerations & Precautions

• Discontinuation Warning: Because this unit is phased out, sourcing brand-new spares requires checking legacy or surplus inventories. For active design projects, migrate directly to the ET 200SP catalog.
• Adjusting Overload Currents: The current-dependent overload release dial must be adjusted precisely to match the motor’s actual Nameplate Full Load Amps (FLA) within the 2.2–3.2 A window.
• Plugging Constraints: Never plug or unplug the starter module into the ET 200S terminal module assembly while the main load voltage (400V) or auxiliary power supply is active, to prevent severe contact arcing.
• Heat Dissipation: Ensure proper alignment and check the configuration limits regarding “derating” when mounting several high-density motor starters side-by-side in high ambient temperatures.

Product Applications

The 3RK1301-1DB00-0AA2 is primarily used inside decentralized control cabinets handling small distributed power loops:

• Conveyor Systems: Driving small three-phase motors powering roller tracks, belt conveyors, and cross-transfers in logistics hubs.
• Pump and Fan Control: Fixed-speed operations of low-power auxiliary fans or fluid supply pumps in factory floors.
• Packaging Machinery: Controlling indexing feeds or localized motorized adjustments on manufacturing lines.
• Material Handling: Small lifting units and cross-travel motors in basic automated handling gantries.
