        More Information

        Overview Manuals Local Control Event Records Idle Management Applications

        Features:

        • The starter supports electronic overload supervision.
        • PROFIenergy functions support coordinated load shutdown during idle periods.
        • An optional 3DI/LC module adds local-control inputs.
        The current setting of 3RK1308-0BD00-0CP0 is part of the motor-protection configuration. The upper setting limit must not be treated as the default for every connected motor.

        Current warning and trip thresholds perform different tasks on 3RK1308-0BD00-0CP0. A warning condition and a shutdown condition are not interchangeable events.

        Phase asymmetry and blocking supervision address different motor conditions in 3RK1308-0BD00-0CP0. Their responses supplement the thermal overload model rather than replacing its configuration.

        The Siemens 3RK1308-0BD00-0CP0 ET 200SP High Feature Reversing Starter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Siemens 3RK1308-0BD00-0CP0 ET 200SP High Feature Reversing Starter Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        Give local commands the defined control priority

        • Accessory requirement: Local control uses the optional 3DI/LC module.
        • Control selection: The LC input selects local operation and gives it priority over fieldbus commands.
        • Leaving local mode: Return from local control requires the local-control selection to be inactive and the motor OFF command condition.
        • Accessory removal: Removing the input module while it is controlling a running motor stops the motor.

        Separate fault, trip and operating-event histories

        • Fault history: The fault log records fault information in its assigned data record.
        • Trip history: Trip events are recorded separately from the fault history.
        • Operating events: The event log provides an additional record of operating events.
        • Reading order: The circular logs place the newest entry first and identify entries by operating-hour time information.

        Use PROFIenergy for the planned idle interval

        • Pause command: PROFIenergy provides a command path for shutdown during planned idle periods.
        • Load state: The function acts on the motor-starter load rather than changing the motor current setting.
        • Measured values: Motor-current information is available through the associated measurement functions.
        • Program integration: The control program uses the applicable PROFIenergy functions to coordinate the idle sequence.

        Use the motor-control scenarios identified for the starter

        • Conveying: Motor-driven conveyor systems are included in the application range.
        • Logistics: Logistics equipment can use distributed motor-starter control.
        • Production machinery: The starter application range includes production machines.
        • Machine tools: Machine-tool motor control is also included in the supported application context.
        Description
        Within a SIMATIC ET 200SP station, Siemens 3RK1308-0BD00-0CP0 switches the direction of a motor as a High Feature reversing starter. Electronic overload protection supervises motor loading alongside the direction commands.

        The hybrid switching circuit of 3RK1308-0BD00-0CP0 combines semiconductor devices with bypass relays. Semiconductors handle the switching transition, while relays carry current during continuous operation; the switching and steady-state paths therefore use different parts of the circuit.

        Direction changes in 3RK1308-0BD00-0CP0 are interlocked so that clockwise and counterclockwise paths are not switched on together. The interlock interval belongs to the reversing sequence rather than the thermal overload calculation.

        The thermal motor model inside 3RK1308-0BD00-0CP0 evaluates measured current using the configured rated operational current and trip class. An overload trip and its cooling period are separate from a direction-change interlock, and the selected trip class does not disable intrinsic device protection.

        Technical notes
        The Siemens 3RK1308-0BD00-0CP0 starter supports a separately fitted 3DI/LC module for local control and additional digital inputs.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        May 3RK1308-0BD00-0CP0 be installed between a frequency converter and its motor?
        That installation is not permitted for 3RK1308-0BD00-0CP0; frequency-converter loads are excluded, and the starter must not be placed in the converter-to-motor connection.
        Why does an overload trip on 3RK1308-0BD00-0CP0 prevent an immediate restart?
        The overload response of 3RK1308-0BD00-0CP0 includes a cooling period. Resetting a command does not eliminate the thermal-model cooling requirement.
        Does an unlit ST/OL indicator on 3RK1308-0BD00-0CP0 prove that the motor shaft has stopped?
        An OFF indication on 3RK1308-0BD00-0CP0 reflects the starter command or operating state; it is not proof of mechanical standstill at the motor shaft.
        What happens to 3RK1308-0BD00-0CP0 when its controller enters STOP?
        In automatic operation, the configured CPU-STOP response for 3RK1308-0BD00-0CP0 determines whether the last value is retained or a zero substitute value is used; the response must not be assumed.
        Can selecting CLASS 10 on 3RK1308-0BD00-0CP0 prevent every early device trip?
        Intrinsic device protection remains active on 3RK1308-0BD00-0CP0. At higher current settings it can act before the selected motor-overload trip-class interval has elapsed.
