Trip class 10A/10E (preset) / 20E per IEC 60947-4-2 gives you the choice: 10A for standard-start loads like pumps and fans, 10E for electronic overload matching, or 20E for high-inertia loads that need a longer acceleration ramp without nuisance tripping. The voltage ramp, soft torque, and pump ramp down features let you dial in the start profile — soft torque reduces mechanical shock on geared drives, pump ramp down prevents water hammer on discharge lines. ## Fieldbus pick — PROFIBUS, Modbus, EtherNet/IP on one unit This soft starter carries PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP onboard — no separate communication module needed for any of those four protocols. PROFIenergy is available when paired with the PROFINET standard communication module. The remote reset by cycling the control supply voltage means you can clear a fault from the PLC without a site visit — useful on remote pump stations or conveyor lines. Error logbook is supported, but only with special accessories — factor that into the BOM if you need event history for predictive maintenance. ## ATEX, IECEx, and the hybrid switching device classification ATEX and IECEx approval (both marked Yes) means this soft starter is certified for use in potentially explosive atmospheres — Zone 2 or Zone 22 typically, depending on the installation. The hybrid switching device category means it uses both electromechanical and semiconductor elements for the start sequence, then bypasses to the contactor for steady-state running. UL and CSA approval are both present, so it lands in North American panels without a separate evaluation. CE marking covers the European market. Service factor is 1 — no built-in overload margin beyond the set current. The minimum load is 15% relative to the smallest settable Ie, so don't try to run a fractional-horsepower motor through this unit. ## Mounting and cooling — screw fixing, derating above 40 °C Screw fixing to the mounting plate — no DIN rail snap-on here. The unit is 282 mm deep, 160 mm wide, 230 mm tall, with 100 mm clearance upwards, 10 mm forwards, 75 mm downwards, 5 mm at the sides, and 0 mm backwards. That 0 mm backwards means it can sit flush against the back panel. Mounting position is vertical with the mounting surface rotatable ±90° and tiltable ±22.5° front-to-back — gives flexibility in tight cabinets but keep the derating curve in mind if you tilt it. Shock resistance is 15 g / 11 ms, dropping to 12 g / 11 ms if contact lifting is a concern — fine for most industrial panels but check if the application has repeated hammering or press impacts. No official successor or cross-reference to the alternate MPNs listed (6ED1052-1MD08-0BA1, 6ES7517-3FP00-0AB0, 6ES7214-1BG40-0XB0) — those are from different Siemens product families (LOGO!, S7-1500, S7-1200) and are not functional replacements for a soft starter. The 3RW5072-2TB15 is the right part for the motor-starting BOM line.","metaTitle":"Siemens 3RW5072-2TB15 Soft Starter, 90A Min, 200-600V, ATEX","metaDescription":"Siemens 3RW5072-2TB15 soft starter, 90 A minimum, 200-600 V, ATEX & IECEx approved.
