ASB404R

Overview

The ASB404R is a Type 1 splitter box manufactured by Hoffman Enclosures, Inc. Constructed from steel with ANSI 61 grey polyester powder paint, it measures 22 inches in length, 22 inches in width, and 6 inches in depth. The unit features a standard hinge and pull latch. It is rated for 600V and supports a main lug capacity of 400A, with branch lugs rated at 285A. Designed for indoor use, the enclosure splits feeder circuit conductors into multiple branch circuits and includes pre-installed terminal blocks compatible with three- and four-wire configurations.

Feature Summary

• Splits feeder circuit conductors into multiple branch circuit conductors
• Includes pre-installed terminal blocks for three- and four-wire power systems
• Constructed from 16 or 14 gauge steel with corrosion-resistant finish
• Features various combination knockouts on all four sides for flexible wiring access

Applications

• Indoor electrical distribution panels
• Splitting feeder circuits to branch circuits
• Industrial control enclosures requiring Type 1 protection
• Commercial building electrical infrastructure

Procurement Notes

Verify that the application environment remains indoors, as this Type 1 enclosure lacks weatherproofing. Confirm voltage requirements do not exceed 600V and current loads align with the 400A main and 285A branch ratings. Ensure physical dimensions fit the designated mounting space. Check knockout configurations against planned conduit entries. Validate that the steel construction meets local corrosion resistance standards for the specific installation site.

Selection Notes

Select this model when indoor conductor splitting is required without environmental sealing. Compare against IP-rated alternatives if outdoor exposure is possible. Consider the 22x22x6 inch footprint for spatial constraints. Evaluate the 400A rating against total load calculations. Verify compatibility with existing busbar systems if integrating into larger assemblies. Assess the need for additional accessories like gland plates or mounting rails based on internal component layout.

Part Context

This splitter box belongs to the Hoffman Enclosures line of industrial electrical hardware. It serves as a passive distribution component within larger electrical systems. Unlike active devices, it provides structural support and connection points for conductors. The product is part of a broader family of NEMA Type 1 enclosures designed for general indoor industrial environments where dust and falling debris are the primary concerns.
