AST5404R

Overview

The AST5404R is a splitter trough manufactured by Hoffman Enclosures, Inc., designed for indoor electrical distribution applications. Constructed from painted steel with a surface gray finish, this unit measures 60 inches in length, 10 inches in width, and 6 inches in depth. It features a standard hinge configuration without a latch mechanism. The component is rated for an amperage of 175/400 A and originates from Mexico. This enclosure serves as a modular section for power distribution systems.

Feature Summary

• Constructed from painted steel for durability
• Designed for indoor installation environments
• Includes a lid for component protection

Applications

• Indoor electrical power distribution
• Modular splitter trough assembly
• Surface mounting installations

Procurement Notes

Verify the specific amperage rating requirements against the 175/400 A specification before procurement. Confirm that the indoor-only design aligns with the installation environment, as outdoor exposure may compromise the painted steel construction. Ensure the standard hinge and non-latch configuration meets security needs. Check for compatibility with adjacent trough sections to maintain continuous power distribution paths.

Selection Notes

Select this model when a 60-inch modular section is required for indoor splitter trough systems. The 10x6 inch cross-section accommodates standard busbar arrangements. Consider the lack of a latch if high-security access is not required at this specific segment. Verify that the 400 A rating suffices for the intended load distribution within the larger assembly context.

Part Context

This splitter trough is part of Hoffman's modular enclosure family, allowing for scalable power distribution setups. It functions as a connecting or terminal segment within larger trough networks. The design prioritizes ease of integration with other Hoffman components, facilitating flexible system expansion and maintenance access in industrial or commercial settings.

Replacement Considerations
