Mersen FSPIN1 – Frequently Asked Questions

1) Is the Mersen FSPIN1 power distribution block UL listed for control panel work?
The FSPIN1 is listed to UL 1059, the standard that covers terminal blocks used for power distribution, so it can be specified in code-compliant industrial control panels and enclosures. If your panel drawing calls for a UL 1059 listed block, this one meets that line item.
2) What short circuit rating does the Mersen FSPIN1 distribution block carry?
10 kA standalone. That is the fault current the block itself is rated to withstand, so the available fault current at the point where you land it needs to be at or below 10 kA, or the block has to sit behind upstream protection that brings the let-through within that figure.
3) What is the difference between the Mersen FSPIN1 and the Square D Linergy 9080LB power distribution block?
Both are power distribution blocks used to split an incoming feed inside a panel, but they are specified differently. The Mersen FSPIN1 is part of the FSPDB finger-safe series, UL 1059 listed with a 10 kA standalone short circuit rating and a compact body measuring 2.05 in long. The Square D unit is from the Linergy 9080LB series and is configured as a 3-pole block, so it is the one to look at when you need three poles landed in a single housing. Choose the FSPIN1 when the panel design calls for a touch-safe profile around energized parts during wiring and maintenance.
4) Can the FSPIN1 be used on a 60 Hz industrial supply?
Yes. The Mersen FSPIN1 is rated for 50/60 Hz systems, which covers standard North American 60 Hz service as well as 50 Hz equipment on export machinery builds.
5) Do I still need to keep a barrier or cover over this block in a panel?
The FSPDB Series is built to finger-safe construction, meaning the current-carrying parts are shrouded against accidental contact while you are wiring or servicing the panel. That is the point of the design: personnel working in a live enclosure are protected from touching energized metal without an added barrier over the block.
6) How much DIN rail or panel space does the Mersen FSPIN1 take up?
It is a small part: 2.05 in length with 0.14 in width and height, and 0.01 lb. That footprint is what lets it go into tight control panels and OEM machine enclosures where a larger cast block will not fit.
7) Is a finger-safe power distribution block like the FSPIN1 the right choice for OEM machine wiring?
It is a common fit there. Machine builders and panel shops use blocks like the FSPDB Series to split an incoming feed to multiple loads inside the enclosure, and the finger-safe profile matters because service techs open those panels with the machine energized. The FSPIN1 is UL 1059 listed and rated 50/60 Hz, which covers both domestic and export builds.
8) What part number do I order for the Mersen finger-safe block, and is it the FSPDB series?
Order it as Mersen FSPIN1. It is a member of the FSPDB Series of finger-safe power distribution blocks, and FSPIN1 is the manufacturer part number to put on the purchase order.
