AST4124R

Overview

The Hoffman AST4124R is a Type 1 Splitter Trough designed for electrical power distribution. Constructed from gray steel, this unit measures 48 inches in length, 6 inches in width, and 4.5 inches in depth. It features a 125-ampere rating and supports four-wire configurations. The trough includes pre-installed terminal blocks to facilitate the splitting of feeder circuit conductors into multiple branch circuit conductors. This component serves as a structural element within industrial power distribution systems.

Feature Summary

• Facilitates the division of feeder circuit conductors into multiple branch circuits
• Includes pre-installed terminal blocks for three- and four-wire power applications
• Constructed from durable gray steel material

Applications

• Three-wire power distribution systems
• Four-wire power distribution systems
• Industrial feeder circuit splitting

Procurement Notes

Verify the specific manufacturing origin, which may be Mexico, and confirm compliance with local import regulations regarding steel products. Ensure that the 125-ampere rating aligns with the intended load requirements. Confirm that the Type 1 enclosure rating meets the environmental protection needs of the installation site. Validate that the physical dimensions fit the designated space within the larger assembly.

Selection Notes

Select this splitter trough when a robust steel solution is required for splitting high-current feeders in indoor environments. The 48-inch length provides significant capacity for branching connections. Consider the weight and handling requirements associated with the steel construction during installation planning. Ensure compatibility with existing busbar or cable arrangements within the distribution panel.

Part Context

This component belongs to the Hoffman line of electrical enclosures and accessories, now part of nVent. It is specifically categorized as a splitter trough, distinct from standard NEMA boxes. These units are engineered to integrate seamlessly into larger switchgear or distribution panel assemblies, providing organized conductor management.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify dimensional compatibility if considering alternative brands. Ensure the replacement maintains the 125-ampere rating and Type 1 enclosure classification.
