Explosion-proof junction boxes type MVA made of aluminum, meet all the requirements of the standards and are suitable for use in hazardous areas 1 and 2, as well as 21 and 22, as well as in zone 0, for temperature classes T4 and T6.
Explosion protection of intrinsically safe enclosures of type “i” is based on the use of low voltage and the connection of power supply to the enclosure (for example, for data transmission or for telephone communication).
Due to the ignition energy limit, the occurrence of a spark is absolutely impossible. Even a temperature rise or heating of our Ex i junction boxes, assembled with the maximum number of serial contacts, cannot cause an explosion.
Using external grounding, enclosures are included in a potential compensation system. This avoids the occurrence of electrostatic charge and associated sparks.
In order to isolate an intrinsically safe power circuit when installing Ex i housings, you must select blue or blue marked cable glands and blue contacts.
