Motor protection switch MS132...K in screwless push-in spring connection technology with thermal and electromagnetic protection represents the compact and powerful series with high short-circuit breaking capacity for motor protection up to 15 kW (400 V) with a module width of 45 mm. The temperature-compensated device has a rotary handle operation with a clear switch position indicator I/TRIP/0. In addition, MS132...K has a short-circuit indicator. The rotary handle can be directly locked in the 0 position using a padlock. Auxiliary, signal and short-circuit signaling contacts as well as undervoltage and shunt current releases can be installed without tools. Push-in spring variants are available for auxiliary and signal contacts, these also fit the motor protection switches with screw technology. Direct adapters for contactors of the AF...K series allow the simple construction of compact starter combinations. Protective housings and accessories for control cabinet and door installation complete the range. The push-in spring connection terminals allow tool-free and time-saving insertion of the connecting cables for rigid wires and stranded wires with wire end ferrules. Stranded wires without wire end ferrules can also be connected. There is no need to readjust the connections later.
