Motor protection switch MS116 with thermal and electromagnetic protection represents the compact and economical series for motor protection up to 15 kW (400 V) with a module width of 45 mm. The temperature-compensated device has a rotary handle operation with a clear switch position indicator I/0. The rotary handle can be locked in the 0 position using a locking device. Auxiliary and signal contacts as well as undervoltage and shunt current releases can be installed without tools. MS116-HKF1-11 has a front-mounted auxiliary switch with 1NO/1NC contacts. 3-phase rails for 65 A or 100 A and feed blocks for 25 mm2 or 35 mm2 allow several motor protection switches to be fed together. Protective housings and accessories for control cabinet and door installation complete the range.
