ASTB85

Overview

The ASTB85 is a splitter trough block assembly manufactured by nVent HOFFMAN. It features a 6-terminal configuration designed for tapping feeder branch circuits within splitter boxes and troughs. The unit includes a main lug and branch lugs to facilitate circuit distribution. Constructed from aluminum, it supports wire gauges ranging from 14 AWG to 1 AWG for main connections and 14 AWG to 6 AWG for branch connections. The assembly is rated for 600 VAC and carries an ampacity rating of 85 A.

Feature Summary

• Facilitates the splitting of feeder branch circuits into multiple branch conductors
• Integrates main and branch lugs for direct connection in splitter troughs
• Constructed from aluminum material for durability

Applications

• Tapping feeder branch circuits in splitter boxes
• Distribution within electrical splitter troughs
• Branch circuit termination in industrial enclosures

Procurement Notes

Verify that the specific application requires an 85-amp rated aluminum block assembly. Confirm compatibility with existing splitter trough dimensions and terminal configurations. Ensure the voltage rating of 600 VAC meets system requirements. Check wire gauge ranges against installed cabling specifications. Consult official nVent HOFFMAN documentation for detailed mechanical drawings and installation guidelines before procurement.

Selection Notes

Select this component when a dedicated splitter trough block is required for circuit distribution. The 6-terminal layout suits applications needing one input split into multiple outputs. Aluminum construction offers weight advantages over steel alternatives. Verify that the 85-amp capacity aligns with the feeder load. Consider the 600 VAC rating for standard low-voltage industrial power distribution systems.

Part Context

This part belongs to the Hoffman ASTB series of junction box accessories. These assemblies are designed to work within larger enclosure systems, specifically splitter boxes and troughs. They serve as critical interconnection points for managing high-current feeder lines. The series provides standardized solutions for branching circuits without requiring custom wiring modifications.
