The required clearance around the unit is 100 mm upward, 75 mm downward, 10 mm forward, and 5 mm at the sides, with zero clearance needed backward. That zero-backwards spec means it can sit flush against a backplate, which helps when you're stacking multiple starters in a row. The ATEX and IECEx certifications (both marked Yes) mean this starter is approved for use in potentially explosive atmospheres — not just the standard industrial floor. If your line runs in a Zone 1 or Zone 2 gas area, or a Zone 21/22 dust area, this unit carries the paperwork to satisfy the inspector. Pair it with an ATEX-rated motor and the right cable glands, and you've got a compliant drive train. ## Motor control features that matter on the floor The trip class is selectable between CLASS 10A, 10E (default), 20E, and 30E per IEC 60947-4-2. For a pump or fan with a long deceleration ramp, you'd set it to 20E or 30E to avoid nuisance trips during the ramp-down. For a conveyor that needs to stop fast, CLASS 10A gives you the tightest protection. The default 10E is a safe starting point for most general-purpose loads. It includes a voltage ramp start, torque control, a breakaway pulse for high-friction loads, and pump ramp down to prevent water hammer. The DC braking feature lets you stop the motor faster than coasting, which is handy on a saw or a centrifuge where you want the spindle to stop before the operator reaches in. The analog output can be set to 4-20 mA or 0-10 V to feed a PLC or panel meter with motor current or torque feedback. The service factor is 1.15, meaning the starter can handle a 15% continuous overload above its rated current without damage — useful if your motor occasionally runs into the service factor band. The accuracy class is 5 per IEC 61557-12, which is standard for industrial metering; the current measurement is good enough for energy monitoring but not for billing-grade accuracy. ## Fieldbus and communication options This unit supports PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP natively — no separate communication module needed for those protocols. If you're on a PROFINET network, the PROFIenergy feature is available when paired with the PROFINET communication module, letting the drive participate in energy management profiles during idle periods. The event list and error logbook store the last several faults, which saves you from chasing intermittent trips with a laptop. Firmware updates are supported in the field, so you can add features or fix bugs without swapping the whole unit. The parameterizable digital inputs (4 available) let you configure start/stop, reset, or speed reference selection without rewiring — just change the parameter number. It carries CE marking, UL approval, and CSA approval, so it's accepted in the EU, US, and Canada without additional certification work. The ATEX and IECEx marks add the hazardous-location coverage. No pin-compatible direct alternative exists within the same SIRIUS family at this rating — if you need a drop-in replacement, this is the one.","metaTitle":"Siemens 3RW5548-2HA14 Soft Starter, 200-480V, ATEX, Active","metaDescription":"Siemens 3RW5548-2HA14 soft starter, rated 200-480 V, ATEX and IECEx certified, trip class 10A/10E/20E/30E.
