Siemens 6SE6440-2UC13-7AA1 Soft Starter 3 Phase

Siemens 6SE6440-2UC13-7AA1 is a Micromaster 440 frequency converter designed for precise control of three‑phase motors. It is rated for 0.37 kW (0.5 HP) output with a 200–240 V AC three‑phase input at 47–63 Hz, enabling smooth acceleration and variable speed for light to moderate loads. The drive enclosure measures 173 × 73 × 149 mm (H × W × D) and carries IP20 protection, suitable for panel mounting in industrial environments within an operating ambient range of -10 to +50 °C. It provides overload tolerance of 150% for 60 seconds and 200% for 3 seconds, allowing short‑term peak loads during start or brief demand spikes. Ideal for small three‑phase motor control tasks in compact electrical cabinets where soft‑start and speed regulation are beneficial, this 6SE6440‑2UC13‑7AA1 variant integrates with standard Siemens accessories and commissioning workflows to deliver reliable, configurable motor performance.
