GUA series explosion proof junction boxes are normally installed 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 materials used to manufacture the GUA series explosion proof junction boxes have been studied to grant the maximum protection against the highly corrosive agents present in these industries:
- body and over die-casted of copper-free (lower 0.1%) aluminium;
- external epoxy powder coating RAL 7001;
- gasket on cover of silicone;
- internal and external earth screws of stainless steel complete with antirotation washers.

GUA series explosion proof junction boxes can be used in the conduit system installation as simple pulling boxes or equipped with multipolar or modular terminal blocks as junction boxes. There are nine possible hub configurations with two different thread size and type to satisfy any installation requirements.
