Terminal and Junction Boxes Ex d: Flameproof Enclosures

Ex d Terminal and Junction Boxes: Protection That Contains Internal Explosions

In hazardous areas (Zone 1, Zone 2), certain electrical components (such as switches, fuses, or contactors) inevitably spark during operation. The Flameproof (Ex d) protection method is used for their safe housing.

Ex d Terminal and Junction Boxes from Pepperl+Fuchs are specifically constructed to withstand an internal explosion and prevent the transmission of flames or sparks to the surrounding explosive atmosphere. This is a robust solution for ensuring electrical connections and control in the most demanding environments.

The Ex d Protection Principle and Its Advantages

The Flameproof principle relies on the physical isolation of the ignition source from the external environment.

• Extreme Durability: Ex d enclosures are manufactured from thick-walled cast aluminum or stainless steel, guaranteeing the ability to withstand the high pressure caused by an internal gas explosion.

• Safety of Connection: Special seals and precisely machined joint surfaces ensure the controlled cooling of extinguishing gases before they exit, preventing external ignition.

• Functionality: Ex d enclosures are ideal for housing components that cannot be intrinsically safe (e.g., high-power switches, power circuit breakers), making them indispensable for power circuits and control systems.

Types of Ex d Equipment

The Pepperl+Fuchs assortment covers various formats for all needs:

• Ex d Terminal Boxes: For housing terminal connections in circuits where the highest level of protection is required.

• Ex d Control Stations: Individually assembled enclosures with pushbuttons, switches, indicators, and other sparking equipment.

• Ex d Equipment Enclosures: Used to protect switching and measuring devices in hazardous areas.
