The Altistart U01 is a soft start/soft stop device for 3-phase asynchronous motors. It is primarily intended to be combined with TeSys U-Starter controllers. It can be used for motor ratings up to 20 HP for 3 phases (200 V to 480 V AC) and up to 32 A. With a width of 45 mm, it is one of the smallest soft starters on the market. It can be installed almost anywhere. It has an integrated bypass that reduces noise and heat dissipation. The protection class is IP20. It weighs 0.49 kg and has the following dimensions: 45 mm wide, 314 mm high, 170 mm deep. The Altistart U01 is designed for the following simple applications: conveyor belts, pumps, fans, compressors, automatic doors and gates, small cranes and belt-driven machines. It complies with the IEC/EN 60947-4-2 standards and carries the UL, CSA, C-Tick and CCC certifications and the CE marking. It can be easily combined with a TeSys U controller using the VW3G4104 power connector. It is easy to install on a DIN rail. Altistart 01 combines simplicity with easy wiring, quick configuration and efficiency. Reduced machine wear and minimized maintenance times optimize operations. Together with the TeSys Model U, it offers a unique motor starter solution.
