ASTB125

Overview

The Hoffman Enclosures ASTB125 is a splitter trough block assembly rated for 600 VAC. It features one main lug with a 125 A rating and six branch lugs, each rated at 85 A. The unit supports wire sizes ranging from 14 to 1/0 AWG for the main connection and 14 to 2 AWG for branch connections. Constructed from aluminum, this component is designed for use in Type S90Y enclosures.

Feature Summary

• Provides a centralized solution for tapping feeder branch circuits within splitter trough systems
• Integrates main and branch lugs with copper/aluminum connectors secured to insulators
• Facilitates ready-to-populate panel configurations by automating drilling and tapping processes

Applications

• Tapping feeder branch circuits in splitter troughs
• Installation within Type S90Y enclosures
• Construction of automated, ready-to-populate panels and enclosures

Procurement Notes

Verify that the required voltage rating of 600 VAC aligns with the system design. Confirm compatibility with the specific enclosure model, such as Type S90Y. Ensure the selected wire gauge falls within the specified range of 14 to 1/0 AWG for main lugs and 14 to 2 AWG for branch lugs. Check material specifications to confirm aluminum construction meets project requirements.

Selection Notes

Select this assembly when a dedicated block for splitting feeder circuits is required within a Hoffman trough system. The 125 A main capacity suits high-current applications, while the eight total lugs allow for multiple branch outputs. Consider the aluminum material for weight and corrosion resistance benefits in industrial environments requiring Type S90Y compatibility.

Part Context

This component belongs to the Hoffman Splitter Trough Block Assembly series, which are accessories designed for electrical enclosures. These blocks are integral to nVent Hoffman's solutions for creating organized and automated panel setups, allowing for efficient distribution of power from a single feeder to multiple branch circuits within structured trough systems.
