240 A minimum setting, Class 10A/10E/20E trip
The 3RW5077-2AB15: That covers standard global low-voltage networks without a transformer swap between regions.
ATEX, IECEx, and fieldbus options
ATEX and IECEx certified — this unit is listed for explosive-atmosphere installations, so it can sit in Zone 2 or Zone 22 motor starter panels without an additional isolation barrier. 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.
