ABB MS165-80

Motor protection switch MS165 with thermal and electromagnetic protection represents a compact and powerful series with high short-circuit interruption 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 has 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 undervoltage and working current triggers, can be installed without tools. 3-phase busbars for 125 A allow for the common supply of multiple motor protection switches. Accessories for cabinet installation complement the range. Atex certification permits the protection of motors in explosive areas, while UL approval as a "self-protected combination motor controller" expands the application range in North America.
