LUB12
Details
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).
