ABB Motor protection switch

Motor protection switch MS132 with thermal and electromagnetic protection represents a compact and powerful series with a high short-circuit interruption capacity for motor protection up to 15 kW (400 V) with a module width of 45 mm. The temperature-compensated device features a rotary handle operation with a clear switching position indicator I/TRIP/0. Additionally, the MS132 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 undervoltage and operating current releases, can be attached without tools. The MS132-HKF1-11 has a front-mounted auxiliary switch with 1S-/1Ö contacts. Three-phase busbars for 65 A or 100 A and feed blocks for 25 mm² or 35 mm² allow for the joint feeding of multiple motor protection switches. Protective housings and accessories for cabinet and door installation complement the range. Atex certification allows for the protection of motors in explosive areas, and UL approval as a self-protected combination motor controller.
