Motor protection switch MS132...K features a screwless push-in spring connection technology with thermal and electromagnetic protection, representing a compact and powerful series with a high short-circuit breaking capacity for motor protection up to 15 kW (400 V) and a module width of 45 mm. The temperature-compensated device has a rotary knob operation with a clear switching position indicator I/TRIP/0. Additionally, MS132...K includes a short-circuit indicator. The rotary knob can be directly locked in the 0 position using a padlock. Auxiliary, signal, and short-circuit monitoring contacts, as well as undervoltage and operating current releases, can be installed without tools. Push-in spring variants are available for auxiliary and signal contacts, which are also compatible with the screw-type motor protection switches. Direct adapters for contactors in the AF...K series allow for easy assembly of compact starter combinations. Protective housings and accessories for control cabinet and door installation complement the range. The push-in spring connection terminals enable tool-free and time-saving insertion of connection wires for rigid wires and stranded wires with ferrules; stranded wires without ferrules can also be connected. Subsequent readjustment of the connections is not necessary.
