ASTB400

Overview

The Hoffman Enclosures ASTB400 is a Splitter Trough Block Assembly designed for electrical distribution systems. Constructed from aluminum with an unpainted brushed finish, this component facilitates the tapping of feeder branch circuits within splitter troughs. It features a main lug and multiple branch lugs to distribute power. The assembly supports a current rating of 125 A and is rated for 600 VAC operation. It includes six terminals for connection purposes.

Feature Summary

• Facilitates tapping of feeder branch circuits in splitter troughs
• Constructed from aluminum material
• Includes main lug and branch lugs for circuit distribution

Applications

• Electrical distribution systems requiring feeder branch circuit tapping
• Installation within splitter troughs
• Low voltage power distribution (up to 600 VAC)

Procurement Notes

Verify that the required terminal count matches the six-terminal configuration of the ASTB400. Confirm compatibility with existing splitter trough dimensions and mounting requirements. Ensure the application voltage does not exceed the 600 VAC rating. Check if additional accessories or specific mounting hardware are needed for the installation environment.

Selection Notes

Select this model when a split feeder solution is required for branch circuits up to 125 A. The aluminum construction offers durability for industrial environments. Consider the unpainted finish for applications where corrosion resistance or specific aesthetic standards are relevant. Verify space constraints within the splitter trough to ensure proper fitment of the block assembly.

Part Context

This component belongs to the ASB series junction boxes by Hoffman Enclosures, Inc. These enclosures are designed to split feeder circuit conductors into multiple branch circuit conductors. The ASTB400 specifically serves as the internal block assembly for these systems, providing the necessary connection points for safe and organized power distribution.
