It's rated for AC-3 switching duty up to 690 V, with motor power ratings of 180 W at 400 V, 250 W at 500 V, and 370 W at 690 V. The coil is 24 VDC, holding power 4 W. Mounts vertically by snapping onto a 60 mm busbar system — common in SIRIUS feeder panels. Dimensions are 155.1 mm deep, 45 mm wide, 200 mm tall. Clearance needed: 20 mm upward, 10 mm downward, 9 mm to the side; zero forward or backward. That 45 mm width is the standard S00 footprint, so it lines up with other S00 components on the same busbar.","metaTitle":"Siemens 3RA2115-0HD15-1BB4 SIRIUS non-fused motor starter","metaDescription":"Siemens 3RA2115-0HD15-1BB4 SIRIUS non-fused motor starter, Size S00, 24 VDC coil, Class 10, AC-3 690 V.
