Description
Schneider Electric Power base - TeSys U - 12 A - Control screw terminals LUB12
TeSys U standard power base, 3 pole (3NO), 12 A/ 690 V, to be completed with a LUC control unit to form a TeSys U reversing starter controller, for 3-speed motor applications phases up to 5.5 kW at 400 V. Base composed of power contacts, control coil, rotary handle, with a modular design for additional modules to get an "all in one" starter controller with protection functions and basic or advanced control. It is equipped with a connection terminal block and closing shutters that cover the empty cavities. It provides a high breaking capacity Icu 50 kA at 400 V, start-stop control guaranteed for 3600 cycles/hour. Very compact (45mm wide), DIN rail mounting and screw fixing, with a padlockable rotary handle. Certified when used in combination with a LUC control unit (IEC, UL, CSA, CCC, EAC, Marine), compliant with Green Premium (RoHS/REACh).
