Detail CSE-A CSE-AL Series Junction Boxes

CSE-A CSE-AL series junction boxes

The CSE - A and CSE-AL enclosures are normally used in the chemical and petrochemical plants, off-shore platforms, refineries and any other industry where hazardous atmospheres (gas and combustible dust) are potentially present.

The CSE enclosures range has been designed to meet the main requirements of power distribution, monitoring and signalling, and other electrical functions inside the hazardous area of the plant

 

Function

The CSE - A enclosures are normally used form the following main applications:

- control stations    

- emergency call units    

- instrument housings

- circuit breakers    

- switches and changeover switches  

- lighting controls - terminal boxes   

 - electrical housing    

- battery container

 

The CSE - AL (light model) enclosures are used only as terminal boxes.

The CSE -  A enclosures are available in different sizes so to create a large and modular range with different heights. The CSE - A enclosures, jointed together through dedicated flanges, can become a large panel, maintaining the original IP protection.

Starting height 80 mm. the CSE - A series can be equipped with operators (pilot lights, push buttons, switches, ect.) on cover.

 

Costruction

The materials used to manufacture the CSE - A and CSE - AL series have been studied to grant the maximum protection against the highly corrosive agents present in these industries:

- body and cover in  copper-free (lower 0.1%) aluminium alloy

- antiloosening screws on cover in stainless steel AISI 316

- gasket on cover in silicone

- internal fixing screws in stainless steel

 

Accessories

To CSE - A enclosures can be completed with the following accessories:

- internal mounting plate in galvanized steel or stainless steel

- mounting brackets in stainless steel

- internal and external earth screws in stainless steel AISI 316
