NEW ARRIVAL: Siemens SIRIUS 3RW3036-1BB14 Soft Starter Now Available
Model Description
We are pleased to announce the immediate availability of the Siemens SIRIUS 3RW3036-1BB14 soft starter, a robust two-phase-controlled motor control device engineered for smooth acceleration of three-phase asynchronous motors. Rated for 45A and 22kW at 400V AC (40 °C ambient), this S2-frame unit accepts a wide supply voltage of 200–480V AC and a universal control voltage of 110–230V AC/DC. Screw terminals ensure fast, tool-free installation, while the integrated bypass contactor eliminates external contactors, reducing panel space and wiring time. Measuring 160 × 55 × 145 mm and weighing only 1.3 kg, the 3RW3036-1BB14 integrates seamlessly into control cabinets for pumps, fans, compressors, conveyors and machine tools where gentle starting and reduced inrush current are critical .

Key Features
The 3RW3036-1BB14 delivers gentle ramp-up, limiting starting current to 3–5 × rated current and cutting mechanical stress on belts, gearboxes and power networks. An integrated bypass contactor engages at full speed, reducing heat and power loss during run-time. Users can set starting voltage, ramp time (0–20s) and current limit via front potentiometers; Class 10 motor overload protection is built-in, so no external relay is required. An internal thyristor stack provides 600V insulation and 4kV impulse withstand, while IP20 finger-safe terminals and –25°C to +60°C operation ensure robust performance on skids or rooftop HVAC units. CE, cULus, CCC and RoHS approvals validate global projects, and the device offers >30,000 electrical operating cycles for long, maintenance-free service life .
Related Models in the 3RW30 Series
The 3RW30 family offers scalable power within the same mounting footprint. 3RW3037-1BB14 (63A, 30kW) and 3RW3038-1BB14 (72A, 37kW) extend capacity for larger motors, while 3RW3035-1BB14 (50A, 18.5kW) suits smaller drives. For lower voltages, 3RW3036-1AB14 provides 24V DC control, and 3RW3036-1BB04 offers identical ratings with alternative terminal arrangement. All variants share S2 frame dimensions, integrated bypass, and common accessories—auxiliary contacts, shunt trips, undervoltage releases—enabling one-size panel cut-outs and quick power upgrades without mechanical redesign .
