Abstract
A device for the explosion protection of electric motors or similar electrical devices such as pumps, in which the motor has a protective housing and works together with an interconnected sensor accommodated in a separate protective housing. A favorable construction is achieved in that the motor protection housing and the sensor protection housing are configured for protection classes of different levels, the lower protection class being provided for the motor protection housing, and the higher protection class being provided for the sensor protection housing, and the protective device being provided for the lower protection class.
Claims18
