This soft starter ramps motor voltage during start to limit inrush current and mechanical shock, then transitions to full voltage once the motor reaches speed. The 1.1 kW power rating at 230 V AC defines the maximum induction motor it can control under standard starting duty. The 3-pole configuration switches all three phases. A minimum load of 9 % of the rated current is required for reliable operation — below that the soft starter may not detect the motor correctly. The unit operates at 60 Hz and is rated for IP20 in-cabinet use with finger-safe touch protection on the front face. Spring-loaded terminals accept 2x (0.25... 1.5 mm²) solid or 2x (0.25... 1.0 mm²) finely stranded wire. The auxiliary contacts are also spring-loaded, rated for 2x (24... 16) — typically used for bypass or status feedback to the PLC. ## Applications The 3RW30 series is specified for standard-duty starting of three-phase induction motors in pumps, fans, compressors, and small conveyors where a reduced-voltage start is needed but variable-speed control is not required. The 1.1 kW rating suits light industrial and commercial equipment — HVAC fan coils, small hydraulic power units, and packaging-line drives. The 3RW3003-2CB54 is an established Siemens 3RW30 soft starter. No official end-of-life notice is recorded in the evidence; the part remains available through standard distribution channels. RoHS compliance is documented since 01-07-06. For current lead time and minimum order quantities, submit an RFQ — this part is typically sourced to order.","metaTitle":"Siemens 3RW3003-2CB54 3RW30 Soft Starter, 3-pole, 1.1 kW, 230 V","metaDescription":"Siemens 3RW30 soft starter 3RW3003-2CB54: 3 poles, 1.1 kW, 230 V AC, IP20, screw/snap-on mounting.
