Procurement Notes

Verify that the application environment is strictly indoor, as the IP30 rating does not provide protection against water or dust ingress. Confirm that the required amperage rating of 400 A aligns with the system design. Ensure compatibility with existing mounting structures due to the specific 48x10x6 inch dimensions. Check if additional accessories like ground splitters are needed for complete functionality.

Selection Notes

Select this model when a NEMA Type 1 splitter trough is required for indoor environments. The 400 A rating suits moderate current distribution needs. Consider the 48-inch length for cable management space. Verify that the steel material and gray finish meet aesthetic and corrosion requirements for the specific installation site.
