Kraus & Naimer is a manufacturer of electrical switches, founded in 1907 and headquartered in Vienna, Austria. As a specialist for lowvoltage industrial switches, we offer both standardized and customized switching solutions. We can customize your switches by adding different extras such as padlock devices, keylock devices, auxiliary contacts und much more. As a manufacturer, supplier, and partner of choice for main switches, control and repair switches, as well as switch disconnectors, we will find the ideal solution for almost every application. Our main switches ensure reliable switching for your system. Thanks to our robust control switches, your custom system will be efficiently managed, even in the most demanding applications and harshest environmental conditions. The compact switch disconnectors provide safe disconnection under load for all low-voltage applications. Our repair and safety switches are essential components for switching off machines before maintenance. We are a trusted partner for customers from various sectors such as railways, vehicles, conveyor and lift systems as well as mechanical engineering, power generation and power distribution systems. We maintain a global production and distribution network with around 900 employees in order to offer you the best service possible.

4 EMC-COMPLIANT CONNECTION EMC-compliant connection of frequency-controlled motors Our maintenance switches according to IEC 60204 and VDE 0113 for EMC-compliant connection of frequency-regulated motors offer many advantages: Preventing faults Thanks to the EMC-compliant add-ons, the development and propagation of electromagnetic disturbance is minimized. This is essential, when frequency converters (FC) are used, for example: To control the speed of motors employed in production facilities To regulate pump and fan speed in building technology To efficiently feed energy into the grid of wind and solar power plants Easy and safe installation UOur switches are equipped with extensively connected shield clamps or with bolt clamps, which ensure continuous shielding. Our switch disconnectors are available in robust plastic enclosures (IP 66/67), ensuring an easy and safe installation. Easy Retrofitting Our shield clamps can be mounted on both sides. The scope of delivery includes shield feed-through, two shield clamps and corresponding screws. Our maintenance switches can be retrofitted with shield feed-through kits. Contact our sales team to determine if retrofitting is possible for your switch.

6 NOTES For the rating of the switch please note that the motor may have approx. 10 % higher charging rate due to the higher loss in FU-operation e.g. a motor with 7,5 kW rating the motor current has to be determined with 16,7 A instead of 15,2 A. Each Maintenance Switch has as standard 2 auxiliary contacts, 1 NC and 1 NO. Via the NO (20 ms leading) the FU can be switched off before the main contacts of the switch open. The configuration of the Maintenance Switch between FU and motor allows the use as Disconnector up to 400 Hz and as Load Switch at frequencies from 40 Hz to 100 Hz. Maintenance Switches for EMC-compliant connection of FU-regulated drives are available either with shield clips (KS- and KL-enclosure) or with clips mounted on DIN-rails (STM-enclosure). These clips are used to continue the cable shield circuit through the enclosure. Notes < Back to the table of contents >
