ASB123R

Overview

The Hoffman Enclosures ASB123R is a Type 1 splitter box designed to distribute feeder circuit conductors into multiple branch circuits. Constructed from steel with an ANSI 61 grey polyester powder paint finish, it features a main lug rated for 125 A and three branch lugs each rated for 110 A. The enclosure dimensions are 12 inches by 12 inches by 4 inches. It includes pre-installed terminal blocks to facilitate the connection of three- and four-wire configurations, ensuring organized power distribution in industrial settings.

Feature Summary

• Splits single feeder circuit conductors into multiple branch circuit outputs
• Includes pre-installed terminal blocks for simplified wiring
• Features durable ANSI 61 grey polyester powder paint finish

Applications

• Industrial power distribution panels
• Commercial electrical infrastructure
• Facility management systems requiring branch circuit splitting

Procurement Notes

Verify that the required wire gauge matches the lug ratings of 125 A for the main input and 110 A for the branch outputs. Confirm the installation environment meets Type 1 indoor requirements. Ensure the physical space accommodates the 12x12x4 inch dimensions. Check local electrical codes for compliance with splitter box usage in your specific application context.

Selection Notes

Select this model when a single high-amperage feed needs to be divided into lower-amperage branches without complex custom fabrication. The integrated terminals reduce assembly time compared to bare enclosures. Consider the steel construction for standard indoor durability. Evaluate if the 125 A main capacity aligns with the upstream supply protection device rating.
