Basic devices TeSys U. Basic device, TeSys U, 32A, without terminals. Rated power 0.1-15 kW, rotation directions 1, MTZ 13, control voltage –. Universal basic devices with pre-wired switching and protection combination, standard up to 12 / 32 A and with 2 auxiliary contacts (1 NO + 1 NC). Construction width up to 15 kW only 45 mm (direct and reversing starter), complete coordination according to IEC 947-6-2 (weld-free). TeSys U is a complete motor outlet that includes the functions of motor protection switch and contactor. With only two basic devices, the power range from 0.1-15 kW is covered. The trick The control voltage and current range only need to be determined at the last second by a pluggable control unit.
