Terminal and Junction Boxes Ex: Safe Communication and Branching in Hazardous Areas

FieldConnex® Ex Terminal and Junction Boxes: Reliable Signal Distribution in Zone 1/2

Reliable distribution of power and signals is critical for any automation system, especially in hazardous areas (Zone 1, Zone 2, Zone 21, Zone 22). Terminal and Junction Boxes from Pepperl+Fuchs are a versatile solution that ensures safe and efficient cable connection, reducing complexity and installation costs on site.

These products are specifically designed for operation in aggressive and dangerous environments, guaranteeing longevity and the highest degree of explosion protection.

Advantages and Protection Technologies

The main function of these boxes is to protect terminal connections from sparking and overheating, which is key in Zone 1/2.

• Increased Safety Method (Ex e): Most terminal boxes utilize the Ex e (Increased Safety) method, which ensures that internal components (terminal blocks, wires) will not generate sparks and will not heat up to dangerous temperatures during normal operation. This is the ideal solution for reliable, simple connections.

• Connection Versatility: The boxes can be equipped with terminal blocks for connecting standard, power, and even intrinsically safe (Ex i) circuits, providing flexibility in system design.

• High Terminal Density: Thanks to optimized design, some models allow housing up to 1200 terminals in a single compact enclosure, significantly saving space in control cabinets and on-site.

Construction and Modularity

Pepperl+Fuchs offers a wide selection of materials and configurations for all operating conditions:

1. Enclosure Materials:

   • Non-Metallic (Polyester): High resistance to chemicals and corrosion, light weight, ideal for aggressive environments.

   • Metallic (Stainless Steel and Aluminum): Maximum mechanical strength and durability, necessary for harsh industrial conditions.

2. Ready-Made Solutions and Assembly:

   • Boxes are supplied both as empty enclosures for custom mounting and as pre-assembled and certified solutions (e.g., small distribution panels or control stations).

Using certified terminal boxes supplied by CSC-Automation LLC significantly reduces engineering time and ensures fast installation on site.
