Protecting motors against overheating
ABB’s CM-MSx.xx range of thermistor motor protection relays monitor the winding temperature of motors. PTC sensors integrated in the motor windings directly measure the motor heat. This direct temperature measurement enables the thermistor motor protection relays to evaluate various motor conditions such as overheating, overload and insufficient cooling. ATEX approval is also available for products used in hazardous areas.
