The purpose of a motor protection switch (MSS) is to protect electric motors from overload. This can be a form of thermal overload caused by a mechanical overload. But it is also necessary to prevent non-starting or failure of external conductors with the help of a motor protection switch. Monitoring is therefore implemented thermo-mechanically, thermo-electrically or electronically.

Motor-protective circuit breakers are used, for example, with three-phase motors. They always have an overcurrent and a short-circuit current release device, and in some cases also an undervoltage release.

Buy motor protection switches - what to consider?


If you are looking for a suitable motor protection switch, it is important to take a close look at the electric motor to be connected. After all, the choice of the right motor-protective circuit breaker depends on the rated current of the motor. In addition, various standards may have to be observed. For example, if the motor-protective circuit-breaker is to provide overload protection and short-circuit protection for the cable and the motor. In this case, the motor protection switch must be installed at the beginning of the motor allocation in accordance with DIN VDE 0113.
