Siemens 3RW3013-1BB04 SIRIUS Soft Starter — Size S00, 3.6 A, Integrated Bypass
The Siemens 3RW3013-1BB04 is a SIRIUS soft starter in frame size S00, rated 3.6 A at 40 °C with a 24 V control supply at 50/60 Hz. It includes an integrated bypass contact system, meaning the thyristors are shorted after start-up for reduced heat dissipation and longer service life — a feature that matters when the starter runs continuously, as on a conveyor or pump. Clearance: 60 mm above, 40 mm below, 15 mm at the sides. The vertical mounting surface allows ±10° rotation and ±10° tilt front-to-back. Rated insulation voltage is 600 V, pollution degree 3 per IEC 60947-4-2. Derating begins at 40 °C: 3.3 A at 50 °C, 3.0 A at 60 °C.
Main current circuit and auxiliary/control circuit both use screw-type terminals. Solid conductor range: 2x (0.25... 2.5 mm²). Auxiliary contacts: 2x (20... 14 AWG). Front clamping point accepts 2x (16... 10 AWG). Maximum wire length to the motor is 300 m.
Protection and Diagnostics
No built-in motor overload protection or intrinsic device protection — external overload relay required. No adjustable current limitation. Minimum load is 10% of rated current. Fault signal displayed via a red LED. No external reset input. Not suitable for inside-delta circuit wiring. No motor brake output.
