The 24 V DC coil keeps control circuit wiring consistent with standard PLC outputs, and the Class 10 trip characteristic means the overload relay will disconnect before the motor windings overheat during a stalled-rotor start. ## Mounting and panel fit — snaps onto 60 mm busbar systems This starter snaps directly onto 60 mm busbar systems using the supplied 8US1251-5DS10 busbar adapter, with a vertical mounting position specified for proper thermal performance. Dimensions are 45 mm wide × 200 mm high × 155.1 mm deep, with 20 mm clearance required above and 10 mm below for ventilation and wiring access. The supplied link module 3RA1921-1DA00 connects the contactor and overload mechanically and electrically — no separate wiring between the two devices.","metaTitle":"Siemens 3RA2115-1GD15-1BB4 SIRIUS non-fused motor starter","metaDescription":"Siemens 3RA2115-1GD15-1BB4 SIRIUS non-fused motor starter, 24 V DC coil, Class 10 thermal overload, size S00.
