Square D HLN4EBL – Frequently Asked Questions

1) What size opening does the Square D HLN4EBL I-Line blank plate cover?
The HLN4EBL covers a 4.5 inch space on the narrow side of an I-Line panelboard interior. Actual plate dimensions are 4.49 in by 2.83 in, so it fills one 4.5 inch narrow-side breaker position. If your open space is a different height, this is the wrong plate for it.
2) Will the HLN4EBL blank plate work on a Micrologic trip breaker position in an I-Line panel?
Yes. The HLN4EBL narrow-side blank plate is made for Micrologic Trip circuit breaker positions, including J-frame and H-frame breaker types, on Square D I-Line circuit breaker panelboards.
3) What is the difference between a narrow-side and a wide-side I-Line blank plate?
I-Line interiors have breaker mounting on both a narrow surface and the wider face, and the filler plate has to match the surface it mounts to. HLN4EBL is the narrow-surface version, 4.49 in by 2.83 in. For gaps on the wide side of the interior you need a wide-side filler instead, not this part.
4) How many blank plates come in a Square D HLN4EBL order?
HLN4EBL ships as a set of 5 narrow-side blank plates, so one order covers five open breaker positions. Count your open spaces before ordering; a panel with more than five gaps needs more than one set.
5) Do I need a blank plate for unused breaker spaces in an I-Line panelboard?
Open breaker positions leave energized bus accessible through the trim, so they get filled. The HLN4EBL narrow-side blank plate closes a 4.5 inch position on an I-Line interior for a finished, enclosed front on both AC and DC I-Line distribution panels.
6) Is the Square D HLN4EBL blank plate made in the USA and mercury free?
Country of origin on the HLN4EBL is the United States, and the plate is manufactured mercury free. Both points come up on government, healthcare, and education procurement specs.
