The 24 V DC coil is fed through the supplied link module 3RA1921-1DA00, which integrates the control wiring into the starter's footprint — no separate interposing relay needed for the logic-level signal. ## DIN rail snap-on, 45 mm wide Snap-mounts onto standard DIN rail (or screw-mount with the push-in lug). Width is 45 mm, depth 97.1 mm, height 167.2 mm — the S00 frame fits a 45 mm slot in the panel layout, with 20 mm clearance upward and 10 mm downward for wiring and ventilation. Mounting position is vertical; the ambient operating range is -20 to +60 °C, with wider storage and transport limits. Pollution degree 3 suits industrial control panels where conductive dust or condensation is present. ## Wiring and compliance AWG equivalent for the contactor is 2x (20-16), 2x (18-14), or 2x 12. The link module handles the control wiring — no separate terminal block required for the 24 V DC coil.","metaTitle":"Siemens 3RA2115-1BA15-1BB4 SIRIUS Motor Starter","metaDescription":"Siemens 3RA2115-1BA15-1BB4 SIRIUS non-fused motor starter, 750 W at 400 V AC-3, CLASS 10 thermal overload.
