Control voltage is 24 V at both 50 and 60 Hz. An integrated bypass contact system means the thyristors are shunted out after the start ramp — no continuous heat dissipation from the power semiconductors during run. That keeps the enclosure cooler and lets you use a smaller panel or tighter wireway fill than a non-bypassed soft starter of the same rating. ## Mounting and integration — DIN-rail or screw-fixed, S00 footprint The S00 frame at 45 mm width; plan for the 150 mm depth when sizing back-panel clearance. Clearances: 60 mm above, 40 mm below, 15 mm at the sides. Solid conductor range is 2x (0.25 to 2.5 mm²). The front clamping point accepts 2x (16 to 10 AWG). Wire length maximum is 300 m — relevant if the motor is remote from the panel; beyond that, voltage drop on the control wires may cause nuisance dropouts. ## Environmental and compliance — pollution degree 3, storage and operating range The storage limit is for handling and warehousing, not running. Derating starts at 40 °C. Insulation voltage rated value is 600 V. Minimum load is 10% of the rated current — below that, the soft starter may not trigger reliably; size the motor so the start current exceeds 10% of the device rating. No internal motor overload protection and no intrinsic device protection — external overload relay is required per code. ## Lifecycle and sourcing — current production, no LTB signal The 3RW3018-1BB04 is in current lifecycle stage — no last-time-buy or phase-out notice.","metaTitle":"Siemens 3RW3018-1BB04 SIRIUS Soft Starter, 17.6 A, S00 Frame","metaDescription":"Siemens 3RW3018-1BB04 SIRIUS soft starter, 17.6 A at 40 °C, S00 frame with integrated bypass.
