        Overview Manuals Starting Stopping I/O Protection

        Features:

        • Three-phase thyristor control shapes motor acceleration and stopping before the integrated bypass carries running current.
        • Three parameter sets keep separate ramps, torque limits, and current limits available for configured operating cases.
        • Digital inputs, relay outputs, an analog output, and motor diagnostics connect the starter to the control system.
        Siemens 3RW5516-1HA15 regulates all three motor phases instead of switching full line voltage directly at start.

        After acceleration, the bypass inside 3RW5516-1HA15 reduces losses by moving current away from the active thyristor path.

        The chosen parameter set of 3RW5516-1HA15 links each control command with its assigned starting, stopping, and protection behavior.

        The Siemens 3RW5516-1HA15 SIRIUS 3RW55 Soft Starter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Siemens 3RW5516-1HA15 SIRIUS 3RW55 Soft 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.

        Starting and Current Control

        • Voltage ramp: The starter raises motor voltage from the selected initial value over the assigned time.
        • Torque control: The configured torque reference shapes acceleration when this start mode is selected.
        • Current limit: Measured motor current is held near the selected limit during acceleration.
        • Breakaway pulse: A brief higher starting command can release a load before the normal ramp continues.

        Stopping and Braking Functions

        • Soft stop: A controlled voltage reduction extends motor deceleration.
        • Pump stop: The assigned stop profile reduces hydraulic pressure changes in pump systems.
        • DC braking: Direct-current injection produces the configured braking effect after disconnection.
        • Creep speed: Low-speed movement supports positioning or setup in the permitted direction.

        Control Inputs and Status Outputs

        • Digital inputs: Four terminals receive assigned start, reset, selection, or control commands.
        • Relay outputs: Parameterized contacts report operating, warning, or fault states.
        • Analog output: The selected measured quantity is transmitted to an external analog input.
        • Parameter sets: Input logic can select among three stored operating configurations.

        Motor and Installation Limits

        • Thermal model: Motor current and trip-class settings determine the calculated overload state.
        • Phase monitoring: The starter evaluates phase-related supply and motor conditions.
        • Mounting: Vertical orientation and permitted rotation preserve the documented cooling path.
        • Derating: Ambient temperature and duty determine the operational current available at installation.
        Description
        Siemens 3RW5516-1HA15 is a SIRIUS 3RW55 soft starter that controls all three motor phases during starting and stopping. Its thyristor paths shape motor voltage and torque, then the integrated bypass carries the running current after the ramp is complete.

        Three parameter sets in 3RW5516-1HA15 separate different acceleration, deceleration, current-limit, and torque settings without changing the power wiring. The selected start mode determines whether voltage ramp, torque control, current limitation, or a breakaway pulse governs the transition from standstill.

        Power terminals on 3RW5516-1HA15 carry the 200–600 V motor circuit, while the 110–250 V AC control supply powers its electronic control path. Four digital inputs assign control commands, three parameterizable relay outputs and one fixed output report operating states, and the analog output exposes a selected process value.

        Motor protection and diagnostics in 3RW5516-1HA15 relate measured current, selected trip class, phase conditions, and thermal state to the configured motor. Pump stop, DC braking, creep speed, motor heating, trace, and condition-monitoring functions alter how the starter behaves before, during, or after normal rotation.

        Vertical installation of 3RW5516-1HA15 keeps its heat flow inside the documented mounting limits, with permitted rotation and inclination used only within the specified arrangement. Conductor size, terminal tightening, ambient temperature, switching duty, and motor connection determine the usable current and power at the installation point.
