It's a direct starter, meaning it connects the motor directly across the line for start and run, with the circuit-breaker providing short-circuit and overload protection. Size S00 frame keeps the width to 45 mm — that's a single 2.5-module DIN slot, so it wires up clean in a crowded panel without hogging rail space. The 24 V DC coil pulls 4 W holding power, which keeps the control transformer small. ## Duty ratings — AC-3 motor switching and overload protection Rated for AC-3 duty (switching squirrel-cage motors) up to 690 V maximum. The power ratings at 400 V are 60 W, at 500 V are 90 W, and at 690 V are 120 W — these are the motor output ratings the starter can handle at each voltage level, not the contactor's thermal current. That's standard for standard-start induction motors that don't have prolonged acceleration times. The magnetic short-circuit trip handles the instantaneous fault clearing. Operating frequency is 50/60 Hz, so it works on either mains standard without derating. Surge voltage resistance is 6 kV, which covers the impulse voltage for 400 V systems per IEC 60947-1. ## Mounting and panel fit — DIN rail or screw, with clearance numbers The mounting position is vertical only — don't lay it on its side or the bimetallic trip curve shifts. Dimensions are 45 mm wide × 167.2 mm tall × 97.1 mm deep. Clearance requirements: 20 mm upward, 10 mm downward, 9 mm at the sides, zero forward or backward. That 9 mm side gap is tight — adjacent starters can sit almost rail-to-rail, but you need that 20 mm above for the coil terminals and arc chamber venting. Degree of pollution 3 means it's rated for conductive pollution environments — typical in control panels near manufacturing floors where dust and humidity are present. The operating temperature range is -20 to +60 °C, storage -50 to +80 °C. ## Sourcing reality — current production, quoted to order The auxiliary switch extension is available as a factory option (the product extension flag is set to Yes), so if you need additional N/C or N/O contacts for feedback, the 3RA2 platform supports adding them without changing the base starter.","metaTitle":"Siemens 3RA2115-0CA15-1BB4 SIRIUS Motor Starter, 690 V AC-3","metaDescription":"Siemens 3RA2115-0CA15-1BB4 SIRIUS non-fused motor starter, size S00, 24 V DC coil, Class 10 overload, snap-on DIN rail.
