Table of Dimensions and Specifications of Primary Distribution Boxes
This document provides specifications for various distribution boxes including dimensions, mounting sizes, and number of ways.
Primary distribution boxes are available in multiple configurations depending on the number of ways (ports) and intended application. Common types include TOP-TS, TOP-TF, TOP-LS, TOP-PS, TOP-PF, and TOP-S, with capacities ranging from 1-way to 36-ways. Dimensions are generally specified in length, width, and height, and vary by model to accommodate different numbers of ports and mounting requirements .
These boxes are typically made from UL-compliant materials and are designed for industrial environments. Many models offer IP67-rated protection, ensuring resistance to dust, water, and harsh environmental conditions. Some boxes also provide IK10 impact resistance, making them suitable for areas with mechanical stress .
Distribution boxes support M8, M12, and M16 connectors, with options for single or dual pre-wired ports. Standard cable lengths include 1M, 2M, 3M, 4M, 5M, and 10M, with customization available for non-standard lengths. LED indicators for power and function are often included to facilitate monitoring .
Boxes are designed for easy installation, often with pre-wired configurations and flexible mounting options. They are suitable for automation, robotics, and processing facilities, providing a centralized point for power and data distribution .
