The MS165 motor protection switch with thermal and electromagnetic protection represents a compact and powerful series with high short-circuit breaking capacity for motor protection up to 45 kW (400 V) with a module width of 55 mm. The temperature-compensated device features a rotary handle operation with a clear switching position indicator I/TRIP/0. Additionally, the MS165 includes a short-circuit indicator. The rotary handle can be directly locked in the 0 position using a padlock. Auxiliary, signal, and short-circuit alarm contacts, as well as under voltage and operational current releases, can be mounted without tools. 3-phase busbars for 125 A allow for the joint feeding of multiple motor protection switches. Accessories for cabinet installation complement the range. Atex certification allows for the protection of motors in explosive areas, and UL approval as a self-protected combined motor protection switch. EAN: 4013614486104.
