Rated voltage spans 200 to 600 V, covering 208 V North American, 400 V European, and 480/600 V industrial systems without a transformer tap change. ## Fieldbus and control integration Onboard PROFIBUS DP and Modbus TCP interfaces mean the starter talks directly to a Siemens S7-1500 or Rockwell ControlLogix without a gateway — the Modbus TCP port also supports PROFIenergy for coordinated energy management during production pauses. Four parameterizable digital inputs handle start/stop, fault reset, and jog commands; the analog output can be set to 4-20 mA or 0-10 V for feeding motor current or torque to a PLC analog card. Control supply accepts 110-250 V AC at 50 or 60 Hz — no separate control transformer needed when the plant runs 230 V control voltage. ## Starting modes and motor protection depth Voltage ramp start lets you set initial torque and ramp time to dial out mechanical shock on conveyors or pumps; the breakaway pulse delivers a short high-torque kick to break static friction before the ramp begins. Torque control mode regulates motor torque directly rather than voltage — useful for soft starting loads where current limit alone still produces a hard acceleration step. Pump ramp down extends the stop time to prevent water hammer in pipelines; DC braking injects DC into the motor windings for a controlled stop without a mechanical brake. Motor heating function passes a low DC current through the windings when the motor is stopped, preventing condensation in humid environments like washdown or outdoor installations. ## Panel mounting and wiring clearances Footprint is 170 mm wide by 275 mm tall by 152 mm deep — mounts on DIN rail or direct panel with screw terminals rated for solid wire from 1.0 mm² up to 10 mm² on the power connections. Clearance requirements: 100 mm above, 75 mm below, 5 mm at the sides, 10 mm in front, and zero behind — the unit can sit flush against the back panel, saving enclosure depth. ## Diagnostics and compliance documentation Built-in event list and error logbook store the last several fault events with timestamps — the trace function captures current, voltage, and torque waveforms during start-up for commissioning or post-failure analysis. Accuracy Class 5 per IEC 61557-12 means the internal current measurement is within 5% — sufficient for motor protection and energy monitoring without an external CT. Service factor 1.15 allows the motor to run at 115% of rated current continuously without tripping, matching standard NEMA motor service factors. Carries CE, UL, and CSA approvals — covers European, US, and Canadian installations without additional agency review. Firmware can be updated in the field via the PROFIBUS or Modbus TCP port, so the starter can receive new features or bug fixes without hardware replacement.","metaTitle":"Siemens 3RW5516-1HA15 Soft Starter, ATEX, 200-600V","metaDescription":"Siemens 3RW5516-1HA15 soft starter with ATEX/IECEx certification, 200-600V rated, Trip Class 10A/10E/20E/30E per IEC 60947-4-2.
