ATEX (Exe) Zones 1&2

Craig & Derricott has been associated with the design and manufacture of Ex products for more than 30 years.

 

The current product range has been developed to meet the technical requirements of todays market and a great deal of the design consideration has been given to bringing a quality product to the market at a competitive price.

 

General Description

The 'EXZ1' range of enclosed switch-disconnectors are supplied in 'Exe' enclosures manufactured from glass reinforced polyester sealing to IP65 ensuring the product will withstand being installed in the harshest of environments.

 

The operating handles are available in Red/Yellow or Black and can be padlocked in the 'Off' position only. The assemblies come predrilled with three entries as shown on the dimension drawings. Cable glands are not supplied with the isolator assemblies however glands for un-armoured cables can be fitted directly to the standard units while brass earth continuity plates can be ordered separately for use with armoured cables.

 

Available in 25A to 180A ratings the isolating switch interiors are supplied in either 3 or 4 pole formats complete with 1 N/O (Early break) & 1 N/C (Late make) auxiliary contacts.
