The MS132 motor protection circuit breaker with thermal and electromagnetic protection represents a compact and powerful series with a 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 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 under-voltage and operational current releases, can be mounted without tools. The MS132-HKF1-11 is equipped with 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 common feeding of multiple motor protection circuit breakers. Protective housings and accessories for control cabinet and door installation complete the range. Atex certification allows for the protection of motors in explosive areas, and UL approval as a self-protected combination motor protection circuit breaker.
