Mersen FSPDB2A – Frequently Asked Questions

1) What wire sizes will the Mersen FSPDB2A accept on the line and load sides?
Line side is a single box connector taking 2/0 through #14. Load side gives you four openings taking #2 through #14. So one feeder in, up to four taps out per pole. Hole diameters are 0.45 in on the primary and 0.32 in on the secondary, which is the practical limit if you are checking whether a lug or a stranded conductor will physically enter.
2) What torque should I use on the Mersen FSPDB2A set screws?
Torque varies by conductor size. On the primary: 100 in-lb for 2/0 through #1, 80 for #2 through #6, 35 for #8 through #14. On the secondary openings: 80 for #2 through #6 and 35 for #8 through #14. Connectors are tin-plated aluminum, so hitting the stated value matters if you are terminating aluminum conductors and want to avoid a loose joint later.
3) Is the FSPDB2A a single-pole block, and what do I order for a three-phase feeder?
The FSPDB2A is 1-pole. For a three-phase or three-wire distribution you would install three of them, one per phase, which is common practice when panel layout or phase spacing is tight. If you would rather have all three poles in one housing, the Square D Linergy 9080LB is a 3-pole power distribution block.
4) Can I land aluminum conductors in the FSPDB2A, or is it copper only?
Both. The connectors are tin-plated aluminum rated AL/CU, and the 175 A rating is the same on either conductor material, so you do not de-rate when switching to aluminum feeders. Termination is box style on both primary and secondary.
5) I need to distribute three-phase power from one block - is the Mersen FSPDB2A the right choice or should I look at the Square D Linergy 9080LB?
For a single block carrying all three phases, the Square D Linergy 9080LB is the 3-pole option. The Mersen FSPDB2A is a 1-pole block, so a three-phase feeder would take three of them side by side in the panel - each one 3.45 in long by 2.21 in wide by 2.21 in high, so budget the DIN rail or backplate space accordingly. Choosing three singles does give you the option of separating phases across the enclosure, and each FSPDB2A carries the full 1500V AC/DC, 175A rating with one 2/0-#14 primary opening feeding four #2-#14 secondary openings.
6) Does the Mersen FSPDB2A mount on DIN rail or does it have to be screwed to the panel?
Either. The FSPDB2A is built for screw mount or DIN rail, so you can land it on existing rail in a control panel or bolt it directly to a subpanel or back plate. Footprint is 3.45 in long by 2.21 in by 2.21 in, and it weighs 0.7 lb, light enough that rail mounting needs no extra support.
7) Is the Mersen FSPDB2A finger-safe for a panel that gets serviced live?
Yes, it is a UL 1059 finger-safe design, so the current-carrying parts are shrouded against incidental contact during troubleshooting and maintenance. The body is nylon. That is the main reason this block gets picked over an open strap-and-lug arrangement in control panels where technicians work with the door open.
8) Is the Mersen FSPDB2A RoHS compliant for an export machine build?
Yes, the FSPDB2A is RoHS compliant, which is what most OEM panel builders need for equipment shipping into RoHS markets.
