A74BP12

Overview

The Hoffman Enclosures A74BP12 is a universal barrier panel designed for unibody free-standing or floor-mount enclosures with centerposts. Constructed from mild steel with a polyester powder-coated finish, it measures 73.8 inches in height and features a 14-gauge (1.9 mm) thickness. This component provides UL Type 1 construction requirements to minimize incidental contact with high voltage. The package includes top and bottom barrier plates for full-depth separation, effectively reducing risks of electrical shock or arc flash within industrial environments.

Feature Summary

• Provides UL Type 1 construction requirements when installed in compatible nVent HOFFMAN enclosures
• Minimizes risk of electrical hazards such as shock or arc flash through physical isolation
• Includes top and bottom barrier plates for full-depth separation

Applications

• Unibody free-standing enclosures with centerpost
• Floor-mount enclosures with centerpost
• Industrial control panels requiring high voltage isolation

Procurement Notes

Verify enclosure compatibility before purchase, as this panel is specifically designed for units featuring a centerpost configuration. Confirm that the target enclosure supports the required dimensions and structural mounting points. Ensure the installation environment aligns with UL Type 1 standards. Check manufacturer documentation for specific mounting hardware requirements and torque specifications to ensure secure attachment and proper safety compliance during assembly.

Selection Notes

Select this model only if the existing enclosure utilizes a centerpost design, as it is not compatible with standard unibody frames lacking this feature. Consider the mild steel material and painted finish for general industrial use where frequent washdown is not required. Evaluate whether additional insulation or specialized coatings are necessary for harsh chemical or corrosive environments beyond standard indoor applications.
