Abb Thermomagnetic Switch 25.0-32.0A 47904

Abb Thermomagnetic Switch 25-32A 50kA MS116-32

The Manual Thermal Magnetic Motor Switch is also known as a motor protection switch. It is used to turn motors on and off and to protect them from short circuits, overloads and phase failures without the need for fuses.

The rated motor current is set on the device with a selector.
