Rated voltage spans 200 to 480 V, covering common global motor voltages from 208 V North American to 400 V IEC without a separate tap changer. ## Overload protection and trip class selection You can also select 20E or 30E for higher-inertia loads where a longer acceleration time is needed without nuisance tripping. The accuracy class is 5 based on IEC 61557-12, so current measurement error stays within ±5% of reading — tight enough for energy monitoring without a separate CT. ## Fieldbus and analog feedback for line integration Onboard PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP mean it talks to most PLCs without an external gateway — the commissioning engineer sets the IP or node address and the soft starter appears in the device tree. An analog output configurable as 4-20 mA or 0-10 V feeds motor current, voltage, or power to a local panel meter or analog input card — useful when the fieldbus isn't commissioned yet. ## Motor control features that matter for pump and conveyor duty DC braking stops the rotor quickly without a mechanical brake — critical spare for conveyors where coast-to-stop is too long. Voltage ramp and pump ramp down reduce pressure surges in pumping systems, extending seal and pipe life. Torque control and breakaway pulse handle high-breakaway loads like crushers or mixers — the pulse breaks the rotor free, then torque control brings it up to speed smoothly. Motor heating protection models the thermal state of the motor during start and stop cycles, not just running overload — this prevents restarts when the motor is still hot from a previous start. ## Panel fit and clearance dimensions The unit measures 170 mm wide, 275 mm high, and 152 mm deep. Side clearance to adjacent devices is 5 mm; upwards clearance is 100 mm; forwards clearance is 10 mm; downwards clearance is 75 mm; backwards clearance is 0 mm — meaning it can sit flush against the back panel. ## Safety and compliance documentation CE marking, UL approval, and CSA approval are all listed — the unit carries the required marks for European and North American installations. The B10d value is 1,588,000, which feeds into the safety function's PFHd calculation per IEC 61508. The service factor is 1.15, so the soft starter can continuously deliver 115% of its rated current without tripping — matching NEMA motor service factors.","metaTitle":"Siemens 3RW5514-1HF04 Soft Starter, 200-480 V, ATEX","metaDescription":"Siemens 3RW5514-1HF04 soft starter, rated 200-480 V, ATEX & IECEx certified, trip class 10A/10E per IEC 60947-4-2.
