UL and CSA approvals plus CE marking round out the compliance set for North American and European markets. Fieldbus integration is built in: PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP are all supported. PROFIenergy is available when paired with the PROFINET communication module — useful for energy management in automated lines. ## Mounting and environment — screw fixing, 282 mm depth Mounting is by screw fixing with a vertical mounting surface, rotatable ±90° and tiltable ±22.5° front-to-back. Dimensions: 160 mm wide, 230 mm high, 282 mm deep. The 282 mm depth is the key panel clearance number — standard 300 mm deep enclosures fit it with 18 mm to spare for wiring ducts. Shock resistance is 15 g / 11 ms, dropping to 12 g / 11 ms if potential contact lifting is a concern. Clearances: 100 mm upwards, 10 mm forwards, 75 mm downwards, 5 mm sideways — plan the enclosure layout accordingly. Lifecycle status is current production. This is not a legacy or phase-out line — the 3RW5077-2AB15 is an active catalog item from Siemens.","metaTitle":"Siemens 3RW5077-2AB15 Soft Starter, 240 A Min, ATEX, IECEx","metaDescription":"Siemens 3RW5077-2AB15 soft starter, 240 A minimum setting, ATEX and IECEx certified, Class 10A/10E/20E trip, UL/CSA/CE.
