AST6224R

Overview

The Hoffman Enclosures AST6224R is a Type 1 splitter trough designed for indoor electrical distribution. Constructed from mild steel with a gray powder-coated finish, it measures 72 inches in length, 8-1/4 inches in width, and 4-1/2 inches in depth. The unit supports a 225 A amperage rating and accommodates four wires. It features standard hinges without a latch mechanism.

Feature Summary

• Indoor-rated Type 1 protection against falling objects
• Mild steel construction with durable powder-coated finish
• Four-wire capacity for circuit splitting applications

Applications

• Indoor electrical panelboard distribution
• Main feeder splitting to branch circuits
• Industrial control cabinet power management

Procurement Notes

Verify the specific project requirements for indoor-only usage, as this Type 1 enclosure lacks environmental sealing. Confirm that the 225 A rating aligns with the intended load calculations. Ensure the 72-inch section length fits the available rack or panel space. Check if additional mounting hardware or end caps are required for the installation setup.

Selection Notes

Select this model when a rigid, non-environmental splitter is needed for indoor busway or panelboard systems. The 72-inch length allows for extended branching compared to shorter sections. Consider the mild steel material for cost-effective indoor solutions where corrosion resistance is not a primary concern. Verify compatibility with existing rail or mounting systems.

Part Context

This component belongs to the Hoffman splitter trough family, which provides modular solutions for distributing power within electrical enclosures. These troughs are typically used to split main feeders into multiple branch circuits. The AST series specifically denotes steel construction with standardized dimensions for easy integration into larger industrial power distribution architectures.

Replacement Considerations

Direct substitutes may include other 72-inch, 225 A, four-wire Type 1 splitter troughs from Hoffman or compatible manufacturers. Ensure the replacement matches the 8-1/4 inch width and 4-1/2 inch depth for proper fit. Verify that the new unit maintains the same amperage rating and wire configuration.
