That trip class range means you can match the overload protection to the start profile: CLASS 10A for standard starts, CLASS 10E for slightly extended acceleration, or CLASS 20E for high-inertia loads like fans or centrifuges where the start current takes longer to decay. The rated operating voltage spans 200 to 600 V AC, covering common low-voltage three-phase supplies across global installations. This unit carries ATEX and IECEx certification, approved for use in potentially explosive atmospheres. UL, CSA, and CE markings are present. ## Fieldbus and control integration The 3RW5076-2AB05 supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET, giving you broad fieldbus flexibility to drop it into most common industrial networks without a gateway. PROFIenergy is available in connection with the PROFINET standard communication module, useful for energy management during idle phases. An analog output is present, configurable as 4-20 mA or 0-10 V, which can feed motor current or load status to a PLC or HMI. Remote reset is accomplished by cycling the control supply voltage off then on — no separate reset signal wire needed. Auto-reset is also supported, which can be used for unattended restart after a fault clears, though you'll want to evaluate that against your safety circuit design. Mounting is by screw fixing, not DIN rail. The unit measures 160 mm wide, 230 mm high, and 282 mm deep, so it needs a dedicated backplate or sub-panel — plan for that footprint plus the specified clearance: 100 mm upwards, 75 mm downwards, 10 mm forwards, 0 mm backwards, and 5 mm at the sides. Shock resistance is 15 g / 11 ms, with potential contact lifting starting at 12 g / 11 ms, meaning it can handle moderate vibration but not heavy repetitive shock without consideration.","metaTitle":"Siemens 3RW5076-2AB05 Soft Starter, 200A","metaDescription":"Siemens 3RW5076-2AB05 soft starter rated 200A, trip class 10A/10E/20E per IEC 60947-4-2.
