ASBB400R

Overview

The nVent Hoffman ASBB400R is a splitter box block assembly designed for tapping feeder branch circuits within splitter boxes and troughs. It features a 600-volt voltage rating and supports wire sizes ranging from 4 AWG to 600 MCM. The unit includes a main lug rated at 400 amperes and branch lugs rated at 225 amperes. Constructed from aluminum, it holds CSA approval and is available in Type 1 configurations.

Feature Summary

• Facilitates the splitting of feeder circuit conductors into multiple branch circuit conductors
• Includes pre-installed terminal blocks with main and branch lugs
• Constructed from aluminum material for durability

Applications

• Splitter box installations
• Trough wiring systems
• Feeder branch circuit tapping

Procurement Notes

Verify that the required voltage rating of 600V aligns with system specifications. Confirm the wire size range of 4 AWG to 600 MCM matches existing cabling. Ensure the 400A main lug and 225A branch lug current ratings are sufficient for the intended load. Check for CSA approval requirements in your jurisdiction. Confirm physical dimensions fit the target enclosure or trough.

Selection Notes

Select this model when distributing power from a single feeder to multiple branches in enclosed environments. Consider the 400A capacity for high-current applications. Verify compatibility with standard splitter box enclosures. Evaluate the need for specific environmental protection types if operating outside standard indoor conditions.

Part Context
