Procurement Notes

Verify that the specific application environment remains indoors, as this Type 12 enclosure is not rated for outdoor or wet locations. Confirm that the 16-gauge steel construction meets the mechanical strength requirements for the intended mounting surface. Ensure that the internal components fit within the 4x4x3 inch dimensions. Check for compatibility with existing conduit entries if pre-drilled holes are required.

Selection Notes

Select this model when a compact, heavy-duty steel enclosure is needed for indoor control panels. The Type 12 rating provides protection against dust, falling dirt, and dripping non-corrosive liquids. Consider the lift-off cover mechanism for frequent access needs compared to hinged designs. Verify that the ANSI 61 gray color matches facility standards.

Part Context

This component belongs to the Hoffman Type 12 Lift-Off Clamp Cover series, designed for general-purpose indoor electrical protection. It is part of a broader range of metal enclosures offered by nVent Hoffman, emphasizing durability and ease of installation for standard industrial applications.

Replacement Considerations

Direct substitutes include other Type 12 steel enclosures with identical 4x4x3 inch dimensions and lift-off cover mechanisms. Ensure any replacement maintains the same 16-gauge material specification and UL 508A listing for compliance.
