The trip class defaults to CLASS 10A per IEC 60947-4-2, with selectable 10E and 20E profiles — meaning it can be tuned to match the thermal limit of the downstream motor during start, not just the breaker coordination. The 15 % minimum load setting relative to the smallest settable Ie gives flexibility for lightly loaded motors without nuisance tripping on the underload detection. ## Fieldbus and control connectivity Dual-protocol native support for PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET standard means this unit drops into most common automation architectures without a separate gateway. PROFIenergy is available when paired with the PROFINET communication module, enabling energy management functions during idle periods. The analog output defaults to 4-20 mA but can be parameterized to 0-10 V via the High Feature HMI, giving the panel builder a single signal path for both current-loop and voltage-input PLC cards. ## Mounting and environmental limits Screw fixing on a vertical mounting surface, rotatable ±90° and tiltable ±22.5° front-to-back — the enclosure layout can adapt to gland-plate orientation without custom brackets. Clearance requirements: 100 mm above, 75 mm below, 10 mm forward, 5 mm at the sides, 0 mm backward — the back can sit flush against the panel wall. Operating ambient -25 to +60 °C with derating above 40 °C; shock resistance 15 g / 11 ms. The derating curve matters for panels with multiple heat sources — a 50 °C cabinet knocks the continuous rating down from the 100 A floor. ## Application features for pump and process control Soft Torque and Pump Ramp Down are built in — the ramp-down profile reduces water hammer on pump stops without an external braking resistor or PLC sequence. Remote reset is available by cycling the control supply voltage, useful for unattended pumping stations. Auto-reset and an error logbook (with special accessories) support fault logging for maintenance intervals. Firmware updates are field-applicable, so the unit can be upgraded without a swap-out. ## Compliance and documentation for cross-border shipment The product category is hybrid switching devices under the SIRIUS brand.","metaTitle":"Siemens 3RW5244-6AC14 SIRIUS Soft Starter, 100 A, 200-480 V","metaDescription":"Siemens 3RW5244-6AC14 SIRIUS soft starter, 100 A minimum, 200-480 V, Class 10A/10E/20E.
