NEW ARRIVAL: Siemens SIRIUS 3RW4026-1BB04 Soft Starter Now Available
Model Description
We are pleased to announce the immediate availability of the Siemens SIRIUS 3RW4026-1BB04 soft starter, a compact two-phase controlled semiconductor starter designed for smooth acceleration of three-phase asynchronous motors. Rated at 25 A and 11 kW (400 V, 40 °C), this S0-frame unit operates from 200–480 V AC mains while being controlled by a universal 24 V AC/DC supply. Screw terminals accept conductors up to 6 mm², and DIN-rail mounting allows fast integration into control cabinets. The integrated bypass contactor eliminates the need for external contactors, reducing wiring complexity and panel space. Its IP20 finger-safe housing measures only 45 × 125 × 155 mm, making it one of the smallest starters in its class—ideal for conveyors, pumps, fans, and packaging machines where space is premium .
Key Features
The 3RW4026-1BB04 delivers gentle ramp-up, limiting starting current to 4–6 × Ie and cutting mechanical stress on belts, gearboxes, and power networks. Users can set starting voltage, ramp time, and current limit via front potentiometers; Class 10 motor overload protection is built-in, so no external relay is required. An integrated red LED signals faults, while two NO auxiliary contacts provide “start-complete” feedback to PLCs. Efficiency is high: losses are only 8 W at 25 A, and the bypass contacts shunt the thyristors once the motor reaches full speed, reducing heat and energy consumption. Ambient operation spans –25 °C … +60 °C, and approvals include CE, cULus, and CCC, ensuring global acceptance .

The 3RW40 family offers scalable power within the same footprint. 3RW4028-2BB14 delivers 18.5 kW / 32 A, while 3RW4036-1BB04 provides 22 kW / 38 A for larger motors. 3RW4026-1BB14 supplies identical 11 kW performance but with 110–230 V AC control coil for sites without 24 V DC. For reversing duty, 3RW4026-2BB04 adds an internal mechanical interlock. All variants share 45 mm width, common accessories (line reactors, braking modules), and identical wiring positions, enabling panel builders to standardize cut-outs and quickly scale power without redesign .
