The MO132 short-circuit circuit breaker with electromagnetic protection represents the compact and powerful series for short-circuit protection of motors up to 15 kW (400 V) with a module width of 45 mm. The device has a rotary handle operation with a clear switch position indicator I/TRIP/0. The rotary handle can be locked directly in the 0 position using a padlock.
