ASTB600

Overview

The Hoffman ASTB600 is a Splitter Trough Block Assembly rated for 600 volts. It features aluminum construction with copper/aluminum connectors secured to insulators. The assembly includes a main lug rated at 600A and branch lugs rated at 125A. Main lug wire compatibility supports (2) 4 AWG-600 MCM or (4) 1/0 AWG-250 MCM conductors.

Feature Summary

• Designed to tap feeder branch circuits in splitter boxes and troughs
• Includes main lug and branch lugs with CU/AL connectors
• Constructed from aluminum material

Applications

• Tapping feeder branch circuits in splitter boxes
• Installation in splitter troughs
• Electrical distribution systems requiring 600V rated blocks

Procurement Notes

Verify the specific voltage rating of 600V and current capacities against project requirements. Confirm conductor material compatibility (copper/aluminum) for both main and branch lugs. Ensure the assembly fits the intended splitter box or trough dimensions. Check for required accessories such as insulators or mounting hardware not included in the base assembly description.

Selection Notes

Select this model when a 600-volt splitter block is required for tapping branch circuits. Consider the 600A main lug capacity and 125A branch lug ratings for load calculations. Verify that the aluminum housing and connector materials meet environmental and electrical standards for the installation site. Compare with other Hoffman splitter assemblies if different ampere ratings are needed.

Part Context

The ASTB600 belongs to Hoffman's line of Splitter Trough Block Assemblies. These components are essential for distributing power from a main feeder to multiple branch circuits within enclosed electrical systems. They are commonly used in industrial and commercial settings where space-efficient circuit branching is necessary.

Replacement Considerations

Direct substitutes may include other Hoffman splitter blocks with similar 600A main and 125A branch ratings. Verify physical dimensions and lug configurations before substitution. Alternative brands may offer comparable specifications but require verification of insulation and voltage ratings.
