Operators (Industrial) MCB/MCCB

The UH-UP explosion proof operators 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 UH-UP explosion proof operators range 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 UH-UP explosion proof operators series have been studied to grant the maximum protection against the highly corrosive agents present in these industries:

  • bushing and shaft, as components directly involved into the explosion proof protection, are made of stainless steel AISI 316. The external body can be made of copper free aluminium or stainless steel
  • external handles and internal leverages activating switches and breakers up to 1000 Amp. are made of stainless steel AISI 316
