Altistart 01 for smooth starting and stopping. Soft starter for asynchronous motors. Rated current 9 A, power 230 V 1.5 kW, power 400 V 4 kW. 400 V, 3-phase network, 50 / 60 Hz, internal control voltage. The soft starter enables the gentle starting of three-phase asynchronous motors and prevents current spikes during the starting phase as well as mechanical load shocks. Typical applications include conveyor belts, conveyors, pumps, fans, compressors, etc. Very easy commissioning, integrated by-pass, optional signaling outputs or internal or external control voltage, boost function for high starting torque.
