It ships with two 3RT2015-1BW42 contactors and a 3RA2913-2AA1 mechanical interlock kit, so the reversing pair arrives as a tested assembly ready for DIN-rail mounting. ## Mounting and panel integration Dimensions are 90 mm wide, 68 mm high, 73 mm deep; clearance gaps of 6 mm sideways and upwards keep heat dissipation predictable in a multi-device row. ## Environmental and compliance Rated for operation from -25 °C to +60 °C and storage from -55 °C to +80 °C, covering most indoor panel environments without forced cooling. Shock resistance is 10.5 g for 5 ms and 6.6 g for 10 ms on both AC and DC supplies — adequate for machine-mounted panels near presses or conveyors. RoHS compliance date is 2009-10-01; the part carries the standard Siemens substance prohibitance declaration.","metaTitle":"Siemens 3RA2315-8XB30-1BW4 SIRIUS Reversing Contactor","metaDescription":"Siemens 3RA2315-8XB30-1BW4 SIRIUS reversing contactor assembly, size S00, rated 3 kW at 400 V AC-3.
