Signalling Contacts Signalling Contacts for use with the TeSys U range to help identify faults in the systems. 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 and added at any time. The plug-in bases can use any LU9 type blocks see stock no. 493-8779 for base option
