Description

Ex enclosed switch disconnector the enclosure has a hinged door, with door lock, made in stainless steel grade AISI 304L available in currents 25A, 40A, 80A and 180A. The enclosure has a hinged door, with door lock. The cover is interlocked, and can not be opened when switch is on.Suitable for outdoor and indoor use. The cable entries are of knock out types. Suitable for outdoor and indoor use. The cable entries are of knock out types.

Allows work with a machine to safely maintain, clean and overhaul it as long as the switch is in the OFF position.The switch is protected by a stainless steel AISI 304L-316L enclosure, waterproof, antirust and with IP66 protection degree. It has a protection “Ex e” and “Ex d”, which allows use in zones with a high explosion risk.

It’s made up of two components:

  • The control component is a selector, which allows the current to go through the circuit or not. The ON position (1) allows the current, so blocks access to the machine through the mechanical blocker.  The OFF position (0) blocks the current, to allow any work on the machine to be carried out.
  • The isolation module allows the current to go through the circuit when the selector is in the ON position, and keep the current when the selector is in the OFF one.

This kind of switch is commonly used in any industry which uses machines, because the electrical circuits and tri-phase asynchronous motors need the energy supply and the installation kept separate, in places considered as potentially explosive, such as zones1, 2, 21 and 22.
The switch is protected by a stainless steel AISI 316L enclosure, specifically designed, waterproof, antirust and with IP66 protection degree. It has a protection “Ex e” and “Ex d”, which allows use in zones with a high explosion risk.

 

The Ex switch rated current is between 25 and 180A.
It can work between two temperature ranges, which give it a higher use capacity.

  • -20°C≤ Ta ≤60°C    
  • -20°C≤ Ta ≤40°C

The Ex enclosure has:

  • The joint between the cover and body, is designed to secure an IP66 degree protection.
  • The selector has an IP65 degree protection.
  • It’s designed with stainless steel AISI 304L.
  • It includes two cable glands with “Ex e” protection in either M25 nickel plated brass or in stainless steel.
  • It has four wall brackets.
  • It has “Ex e” and “Ex d” protection, for use it in zones 1, 2, 21 and 22 with explosive atmospheres with dust and gas.

Discover the advantages

  • Long-life and high resistance
    The enclosures are made of high quality stainless steel , UV resistant and the degree of protection is IP66. Suitable for indoors and outdoors.
  • Prevents electrical accidents
    Features such as padlockable handles and cover interlock allow safe maintenance and installation work.´
  • Quick and easy selection
    Our web based selection enables the user to select the best switch for the application in an easy way.

It is impossible to start the machine when working on it thanks to the mechanical blocking of the disconnector.
It gives a total block.
It’s a necessary device in order to carry out maintaining, cleaning or overhauling.
Enclosure is made in AISI 316L stainless steel for marine or highly corrosive places.
