MULTI-BOX MBP-Ex empty - empty explosion-proof enclosures made of reinforced polyester meet all the requirements for explosion protection and are designed for facilities where explosive concentrations of gases, vapors and dust can occur (zones 1 and 2, as well as 21 and 22).

Explosion-proof empty enclosures MBP-Ex have certificates confirming the structural safety of the mechanical component "enclosure".

Thus, when registering a new explosion-proof product, it will not be necessary to conduct repeated tests and re-confirm the parameter values ​​associated with the housing properties, which greatly simplifies the process of product approval.

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.

Enclosures of type MBA-Ex e can be used for temperature classes T4 and T6.

Temperature class 6 means that even if the contact assembly is heated, the maximum total temperature will not exceed 80 ° C either inside or outside this case.

Thus, combustible gases, vapors and dust are not flammable.

Using the external ground strap, the enclosures are included in the potential compensation system.

This allows you to completely avoid the occurrence of electrostatic charge and associated sparks.

If standards permit, explosion-proof junction boxes of increased degree of protection with the marking “e” can be combined with intrinsically safe circuits marked “i”.

The minimum clearance and creepage distance between the contacts of both power circuits should then be at least 50 mm. In this case, there is no heating of intrinsically safe power circuits.

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 connecting power to the enclosure (for example, for data transfer 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 lead to an explosion.

Using external grounding, enclosures are included in a potential compensation system. This allows you to completely avoid 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.

Explosion-proof aluminum enclosures 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.

Empty MBA-Ex enclosures have an Ex-Component certificate confirming structural safety for use in hazardous areas.

Thus, when registering a new explosion-proof product, it will not be necessary to conduct repeated tests and re-confirm the parameter values ​​associated with the housing properties, which greatly simplifies the process of product approval.

After installing electronic and electrical components in this enclosure, the entire unit must be retested and certified.
