That trip-class range means you can match the thermal overload curve to the motor start profile — CLASS 10 for standard starts, CLASS 20 or 30 for high-inertia loads like centrifuges or crushers. ATEX and IECEx certification qualifies it for explosive-atmosphere zones, so it can sit in a motor control center feeding a pump or conveyor in a classified area without an external isolation barrier. Communication options include Modbus RTU, Modbus TCP, PROFIBUS, and EtherNet/IP, plus PROFIenergy support when paired with a PROFINET communication module. That covers most fieldbus topologies in a single unit — no separate gateway needed for a mixed-protocol line. Dimensions are 210 mm wide, 393 mm high, 203 mm deep. Mounting clearances: 100 mm upward, 75 mm downward, 10 mm forward, 5 mm at the side, and 0 mm backward. The zero backward clearance means it can sit flush against a panel backplane — useful when you're packing multiple starters into a single enclosure. Screw-terminal connections are standard for this class; no special crimp tooling required on site. ## Operating conditions and derating Service factor of 1.15 means the motor can be loaded 15 % above nameplate without tripping the overload protection, common for pump and fan applications where occasional over-speed is expected. ## Control and protection features Built-in DC braking and combined braking allow the starter to stop a motor faster than coast-to-rest — useful for conveyors or spindles where over-travel is a problem. Voltage ramp and pump ramp down give controlled acceleration and deceleration for fluid-handling loads to prevent water hammer. Torque control and breakaway pulse handle high breakaway torque loads like crushers or mixers. Auto-reset and remote reset let the starter re-start after a fault without a manual panel visit — useful for remote or unattended sites. Analog output configurable as 4-20 mA or 0-10 V provides a real-time current or torque signal to a PLC or SCADA. Accuracy Class 5 per IEC 61557-12 means the measurement error stays within 5 % of reading — adequate for monitoring, not for billing-grade metering. Event list, error logbook, and trace function store fault history and trend data for diagnostics. Firmware update capability means the starter can be upgraded in the field without replacing hardware. Approvals include CE, UL, and CSA, covering European, US, and Canadian installations without additional agency review.","metaTitle":"Siemens 3RW5547-6HA04 SIRIUS Soft Starter, 200-480 V, ATEX","metaDescription":"Siemens 3RW5547-6HA04 SIRIUS soft starter, rated 200-480 V, ATEX/IECEx certified, CLASS 10A/10E trip class.
