Square D HCM48TSD – Frequently Asked Questions

1) What size panelboard enclosure does the Square D HCM48TSD trim front cover?
The HCM48TSD I-Line trim front is built for a 48 inch high enclosure and measures 32.25 inches wide. It is a surface-mount dead front, so it lands on the face of the box rather than into a wall opening. Match it to the I-Line enclosure box dimensions before ordering, since a trim front sized for a different box height will not cover the opening.
2) Do I need a UL Listed dead front for an inspected commercial panelboard install?
Inspectors look for a listed dead front assembly, and this Square D I-Line trim front is cULus Listed under UL File E33139 and CE marked. It ships as a factory-assembled dead front, so there is no field fabrication to defend during inspection.
3) I need a flush-mount panelboard front, not surface-mount. What are my options?
The Square D HCM48TSD is a surface-mount trim front, meaning it mounts to the face of the panelboard enclosure rather than sitting in a wall recess, so it is the wrong choice for a flush installation. For a flush application, the ABB AF-F is an AF Series RLP unassembled flush panelboard front. Confirm the flush front matches the enclosure brand and series you are covering before ordering, since fronts are box-specific.
4) Can an ABB AF A-Series front cover be used in place of the Square D HCM48TSD trim front?
No. The HCM48TSD is a Square D I-Line series surface-mount trim front sized 32.25 in wide by 48 in high, built to match I-Line circuit breaker panelboard enclosures. The ABB AF A-Series surface mount panelboard front cover is an ABB A-Series part and is made for ABB panelboard boxes. Panelboard fronts are not interchangeable between manufacturers or series - the mounting pattern, box dimensions, and dead front cutouts are specific to the enclosure line, so an I-Line box takes an I-Line front.
5) Is the Square D HCM48TSD trim front rated for DC distribution as well as AC?
Yes. The I-Line trim front is rated 600VAC and 250VDC maximum, so it can be used on either AC or DC circuit breaker distribution panelboards within those limits.
6) Does this I-Line panelboard front have a hinged door, or is it a solid cover?
It is configured with one door, giving access to the circuit breakers behind the dead front without removing the whole trim. Solid trim fronts without a door require pulling the front off every time you need to reach a breaker, which is why single-door trims are the common choice on panels that get switched or inspected regularly.
7) Can I use this trim front on an existing older I-Line panel during a retrofit?
Yes, this is a standard retrofit part for I-Line circuit breaker panelboards. The deciding factor is the enclosure box, not the breakers: the front suits a 48 inch high box and is 32.25 inches wide, surface mount. If the existing box matches those dimensions, the trim front replaces a damaged or missing dead front without touching the interior.
8) What is the exact part number to order for this I-Line surface trim front?
Order Square D HCM48TSD. That is the single model for this surface-mount I-Line trim front with one door, 32.25 inches wide for a 48 inch enclosure.
9) Is the Eaton P475810 sub-feed breaker cover an alternative to the Square D HCM48TSD?
They do different jobs. The HCM48TSD is a full dead front trim with one door that covers the face of an I-Line panelboard enclosure at 32.25 in by 48 in and carries a 600VAC / 250VDC maximum rating. The Eaton P475810 is a Pow-R-Xpress sub-feed breaker cover for a 600A panel bottom - a partial cover piece for one section of an Eaton Pow-R-Xpress panel, not a complete panelboard front. If you are closing up an entire I-Line enclosure, the Eaton part will not do it.
10) Is the Square D I-Line HCM48TSD trim front made in the USA?
Yes, country of origin on the HCM48TSD trim front is the United States, which matters on public and federally funded jobs with domestic sourcing language in the spec.
11) Do I have to assemble the panelboard front myself, and is there a pre-assembled option?
The Square D HCM48TSD I-Line trim front is factory assembled or ready to install on site, which cuts field labor on the dead front. If you are working on an ABB panelboard instead, the ABB AF-F is supplied as an unassembled flush panelboard front, so plan field assembly time for that one. Assembly state is worth confirming when you are scheduling an energization date around the cover install.
