Distribution Box Fixed Rail

A Distribution Box Fixed Rail is an electrical enclosure or terminal block system designed for secure mounting on a DIN rail, enabling organized and flexible distribution of power, signals, or control currents.

Overview

A distribution box is a component of an electrical system that divides a main power feed into subsidiary circuits while providing protection via fuses or circuit breakers. Fixed rail distribution boxes are specifically designed to be mounted on DIN rails (typically TH35 top-hat rails), allowing modular installation and easy integration into industrial panels, building automation systems, or fiber optic networks .

Types and Features

1. DIN Rail Distribution Boxes

   • Used for electrical or fiber optic connections.
   • Can accommodate pre-assembled cables and adapters, such as LSH/APC fiber adapters, with capacities up to 24 fibers .
   • Mounting options include central or asymmetrical fastening on the rail .
   • Provide mechanical protection, environmental protection, and organized cable management .

2. FIX Distribution Blocks (PTFIX/PTVFIX)

   • Ready-to-connect blocks for power and control current distribution .
   • Available in multiple terminal points (2, 4, 6, 12, 18) and cross-sections (1.5 mm² to 10 mm²).
   • Push-in connection technology allows quick insertion of rigid or flexible conductors.
   • PTVFIX blocks feature lateral feed for flat wiring without bending radii.
   • Compatible with CLIPLINE accessories and available in multiple colors for clear conductor assignment.
   • Some versions include Ex approval for use in hazardous environments .

3. General Distribution Box Features

   • Provide decentralized installation close to the load for energy, signal, or data distribution .
   • Support pluggable installation and prefabrication for faster project realization.
   • Can be used in harsh environments, including moisture-prone areas .
   • Often comply with IEC standards (IEC 61439 for distribution boxes, IEC 61535 for connectors) for safety and reliability .

Applications

• Industrial control panels and automation systems.
• Building energy distribution and smart building installations.
• Fiber optic network termination and breakout points.
• Environments requiring modular, flexible, and space-efficient electrical distribution.

Installation Advantages

• Modular mounting on DIN rails allows easy expansion or replacement.
• Space-saving design suitable for confined panels.
• Maintenance-free operation with push-in or plug-in connections.
• Color-coded terminals improve safety and reduce wiring errors .

In summary, a Distribution Box Fixed Rail provides a versatile, modular, and secure solution for distributing electrical power, signals, or fiber connections in industrial, commercial, and building automation applications, with easy installation and compliance with international standards .
