| Long Description | TeSys U standard power base, 3 poles (3NO), 12A/690V, to be completed with a control unit LUC to form a TeSys U starter controller, for 3-phase motor applications up to 5.5kW@400V. Base composed of power contacts, control coil, rotary handle, with a modular design for additional modules to form a "all in one" starter controller with basic or advanced protection and control functions. It is equipped with a control terminal block, and blanking shutters covering the empty cavities. It provides a high breaking capacity Icu 50kA@400V, start-stop control guaranteed for 3600 cycles/hour. Very compact (45mm width), DIN-rail mounting and screw fixing, with a padlockable rotary handle. Certified when used in conjunction with a LUC control unit (IEC, UL, CSA, CCC, EAC, Marine), Green Premium compliant (RoHS/REACh). | ABB motors are of the totally enclosed, three phase squirrel cage type, built to comply with international IEC and EN standards. Motors conforming to other national and international specifications are also available on request. All production units are certified to ISO 9001 international quality standard as well ISO 14000 environmental standard and confirm to all applicable EU Directives. ABB is one of only a handful of leading motor manufacturers in Europe to have a motor range to meet or exceed the minimum efficiencies stated in the highest level of the EU agreement of low voltage motors. These efficiency levels apply to 2and 4-pole, three phase squirrel cage induction motors rated for 400V, 50Hz with S1 duty class with the output 1.1 to 90 kW, which account for the largest volume on the market. ABB uses class F insulation systems, which, with temperature rise B, is the most common requirement among industry today. The use of Class F insulation with Class B temperature rise gives ABB products a 25° C safety margin. It can also be used to extend insulation life. For instance, a 10 K temperature reduction will extend the insulation life. |
