Operators (Ex 'de') Switches

Explosion Proof Switches

The WH - WP Ex 'de' operators and WA instruments 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 WH - WP - WA range of explosion proof switches has been designed to meet the main requirements of power distribution, monitoring and signaling, and other electrical functions inside the hazardous area of the plant.

Customers can still purchase even if there is no stocks available

Unit Of Measurement (UOM):

The material used to manufacture the WH-WP Ex 'de' operators and WA instruments have been studied to grant the maximum protection against the highly corrosive agents present in these industries:

  • the external components (handle, push-button, diffuser, ect.) are made of high-quality antistatic and UV-protected polymers and provided with EPDM sealing to mantain the IP66 level of protection of whole control station;
  • the internal Ex d/Ex e components are made of high quality thermoplastic and are available for standard installation on cover or, as option, on a dedicated mounting rail;
  • the rated current of Ex switch module is up to 16 Amp. and its mechanical life is 1,000,000 times;
