power base - TeSys U - 12 A - 24 V DC screw clamps control
Description
TeSys U standard reversing power base, 3 poles (3NO), rated 12A/690V, to be completed with a control unit LUC to form a TeSys U reversing 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" reversing starter controller with basic or advanced protection and control functions. It is equipped with a reverser module LU2MB0BL to be supplied with 24V DC, auxiliary signaling contacts (1NO+1NC), a control terminal block, 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).
