Low Voltage Flameproof Motors – FLP Motors

Categories: ,


The use of electrical motors in potentially explosive atmospheres is quite frequent these days. These motors have to be constructed in such a way that there is no risk of an explosion. An Explosion occurs when the following situations occur:
– presence of potentially explosive atmosphere
– existence of a source of ignition
– possibility of transmission of the explosion
