Siemens 3RW3024-1AB14 Soft Starter

Siemens 3RW3024-1AB14 is a SIRIUS cushioned soft starter, Size S0, designed for three‑phase motors and intended to soften startup by ramping current from a 200–460 VAC supply. It offers a 5.5 kW (about 7.5 HP) rating, with a nominal continuous current of 12.5 A at 40°C (11 A at 50°C, 9 A at 60°C), and a 110–230 V AC control voltage. Wiring is performed via screw terminals, and the unit mounts on a DIN rail for compact panel installations. Start and stop times are adjustable from 0 to 20 seconds, allowing controlled acceleration and deceleration to reduce mechanical and electrical stress on driven equipment. This model is positioned for standard soft‑start needs in industrial settings, suitable for 50/60 Hz systems, where compact size and straightforward wiring are important for pumps, fans, conveyors, and other common three‑phase loads.
