A36NTMA3

Overview

The Hoffman Enclosures A36NTMA3 is a terminal block bracket assembly designed for use with Type 4, 12, and 13 enclosures. It provides strong, versatile mounting supports for terminal blocks.

Each kit contains two or three brackets that mount directly to enclosure collar studs using clamping nuts. The components are constructed from mild steel with a powder-coated finish.

Feature Summary

• Provides strong and versatile mounting support for terminal blocks
• Mounts directly to enclosure collar studs using included clamping nuts
• Designed for easy installation within compatible NEMA enclosures

Applications

• Horizontal mounting in 36-inch wide Type 12 enclosures
• Vertical mounting in 36-inch tall Type 12 enclosures
• Terminal block organization in Type 4 and Type 13 enclosures

Procurement Notes

Verify the specific enclosure model compatibility before purchase, as this kit is sized for 36-inch dimensions. Confirm whether horizontal or vertical mounting orientation is required, as this affects the number of brackets included (two or three). Ensure the target enclosure utilizes collar studs for direct bracket attachment. Check for any variations in finish or material specifications if environmental conditions differ from standard indoor applications.

Selection Notes

Select this part only if the enclosure width or height is exactly 36 inches. Compare with A30NTMA3 for 30-inch enclosures. Ensure the application requires terminal block support rather than general component mounting. Verify that the enclosure type (4, 12, or 13) is compatible with the bracket design. Consider the mounting orientation to determine the correct bracket count included in the assembly.
