Square D HLN1BL – Frequently Asked Questions

1) What does the Square D HLN1BL blank plate actually cover on an I-Line panelboard?
HLN1BL is a filler plate for the narrow side of an I-Line panelboard interior, closing out space where no circuit breaker is installed. It is sized at 1.5 by 2.84 inches and ships three plates to a set, so one order covers three open narrow-side spaces. Use it on new installs or when a breaker is pulled during retrofit work and the opening has to be dead-fronted.
2) Will the HLN1BL work on an I-Line panelboard built with Micrologic trip units?
No. HLN1BL is configured for I-Line sections using non-Micrologic trip units. If your panelboard interior is set up for Micrologic trip breakers, this narrow-side plate is not the right filler for that arrangement and you need the plate matched to the Micrologic configuration.
3) What size opening does the Square D narrow-side I-Line blank plate fit?
The plate measures 1.5 by 2.84 inches. That is the narrow-side filler footprint on I-Line panelboard interiors, not a wide-side or full-width cover, so measure the open space in your interior against those two numbers before ordering.
4) Do I get one plate or several when I order HLN1BL?
Each HLN1BL is a set of 3 plates, and they are packaged 30 each per carton for distribution. Count your open narrow-side spaces before ordering so you are not short, and remember you are buying in multiples of three.
5) Is the HLN1BL blank plate RoHS compliant and mercury free for institutional spec work?
It is RoHS compliant with exemptions, in scope for China RoHS, and mercury free. For facility and government procurement that screens on restricted substances, those are the compliance points on record. It is also manufactured in the United States, which matters where domestic-origin preference applies.
6) Is a blank plate required when I remove a breaker from an I-Line panelboard?
Yes, practically speaking. An open breaker space leaves energized bus accessible behind the dead front, so the space gets filled. HLN1BL is the narrow-side filler for I-Line interiors on non-Micrologic trip setups and does exactly that job during maintenance, breaker removal, or panel reconfiguration.
