What is an Ex e Increased Safety?
Ex e is a type of protection for equipment that are applied to explosive atmospheres by preventing high temperatures.
Components that pose sparks are required to exclude in the equipment with this type of protection.
which concerns the surface temperature of enclosures, Ex e focus on controlling the internal temperature of components in the equipment.
Terminals and junction boxes commonly adopt Ex e protection. The primary features as below:
- Eliminate sparking by selecting proper materials, setting adequate spacing between components, and so on.
- Connections between components must be highly integrated.
- The enclosure should better materials to stand up to impact.
- Components used the equipment must be certified too.
- For IP degree, at least IP40 for fully insulated live parts; but, at least IP54 protection for live parts without insulation.
