Minimum settable current is 7.5 A, with a minimum load of 15% relative to the smallest settable Ie — so it handles small motors down to about 1.1 A at the low end of the adjustment range. Rated supply voltage is 200…600 V AC, covering common global line voltages from 208 V to 575 V without a tap-change transformer. ## Fieldbus and control — what connects where Onboard PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET are all supported — the soft starter talks directly to the PLC without an external gateway. PROFIenergy is available when used with the PROFINET communication module. Analog output is configurable as 4…20 mA (default) or 0…10 V when parameterized with the High Feature HMI. Remote reset is done by cycling the 24 V DC control supply voltage. Firmware update capability is built in, and the unit logs errors to an onboard logbook when the special accessory is fitted. ## Panel fit and mounting constraints Mounts via screw fixing (not DIN rail snap-on), so budget for four screws into the backplate. Dimensions are 275 mm high, 170 mm wide, 152 mm deep — allow 100 mm clearance above, 75 mm below, 10 mm forward, and 5 mm to the side for ventilation and wiring access. Operating temperature range is -25…+60 °C, but derate above 40 °C. The unit can be tilted ±10° on a vertical surface, which helps when fitting into tight enclosures. Solid wire terminations accept 2x 1.0…2.5 mm² and 2x 2.5…10 mm² — the larger range covers the power wiring, the smaller covers control wiring. ## Compliance and approvals — what the certs cover Carries UL, CSA, and CE marking — accepted in North American and European installations without additional agency review. Shock resistance is 15 g / 11 ms, with potential contact lifting above 12 g / 11 ms. Service factor is 1.0, meaning no continuous overload margin beyond nameplate — size the motor FLA to match the soft starter setting exactly.","metaTitle":"Siemens 3RW5214-3AC05 SIRIUS Soft Starter, 200-600 V","metaDescription":"Siemens 3RW5214-3AC05 SIRIUS soft starter, 7.5 A min, 200-600 V, Class 10A/10E/20E, PROFIBUS/Modbus/EtherNet/IP, UL/CSA/CE.
