Power Base This is one of the two basic units which is required everytime, together with a control unit. It is independent of the control voltage motor power and incorporates the breaking function Breaking capacity of 50kA @400Vac Short circuit protection Disconnection/isolation Two auxiliary contacts (1NO+1NC) Padlockable 45mm wide Note Current shown is when at a voltage of 440V is utilised. LUB**** series power bases are non-reversing, LU2B**** series are reversing types. Schneider Electric TeSys U The TeSys U is a modular system for motor control; it enables the user to create a customised solution for their control requirements, from a series of standard modules. The plug-in modules allow the assembly and wiring before the selection of motor protection parameters and control voltages, they can be created or changed in seconds by changing the plug-in modules. A host of DOL starting applications can be catered for. Faster design with fewer components needed Quicker panel build with faster assembly time and fewer wires per starter Space saving 45mm width up to 32A (even for reversing) allowing smaller panels Flexible and upgradeable with plug-and-play function modules Voltage and protection parameters can be determined after assembly and wiring Broad band electronic control unit provides improved overload protection with fewer components Expandable plug-and–play diagnostics Total co-ordination for fast return to service after a short circuit fault Tesys model U is easy to select: First choose a Power Base- 12A or 32A, direct on line or reversing. The power base includes 2 auxiliary contacts. Then choose the plug-in protection module by motor full load current and control voltage required. Additional plug in functions can be selected ...
