Mersen FSPDB Series UL 1059 Finger-Safe Power Distribution Block, 1500V

The Mersen FSPDB Series delivers a new level of safety and installation speed for power distribution blocks. Built with a tin-plated aluminum connector body and Nylon insulating housing, these 1-Pole blocks are UL 1059 listed for 1500V AC/DC and achieve an IP20 level of finger-safe protection, eliminating the need for special covers or custom Plexiglas shields on your panels. FSPDBs snap directly onto standard 35mm DIN rail for the quickest possible installation, and since they are modular, any number of poles can be assembled to fit the application. This FSPDB series is available across a Motor FLA range from 175A to 310A, letting panel builders select the block that matches their downstream motor load while keeping the same finger-safe design, Nylon housing, and 1500V UL 1059 listing across every option.

Key Features

  • Motor FLA Range: Available from 175A up to 310A Motor FLA to match a range of panel load requirements while sharing the same finger-safe construction.
  • Finger-Safe Protection: IP20 rated design shields live connections without requiring custom covers or Plexiglas sheets.
  • Modular DIN Rail Mounting: Snaps onto 35mm DIN rail, or can be screw mounted, with multiple-pole assembly pins available for multi-pole panel builds.
  • Durable Construction: Tin-plated Aluminum connectors paired with a Nylon insulating body for reliable, corrosion-resistant performance.
  • Voltage Rating: UL rated 1500V AC and 1500V DC for demanding power distribution applications.
  • Short Circuit Ratings: 100 kA (Class G with 60A fuse), 100 kA (Class CC with 30A fuse), and 10 kA standalone for dependable fault protection.
  • Box-Style Connectors: Box connector type on both the primary and secondary connections for secure conductor termination.
  • Wide Wire Range: Accommodates conductors from 350 mcm & 2/0 down to #14 --- #2, across 2 - 8 openings depending on block size.
  • Frequency: Rated for 50/60 Hz AC/DC operation.

Mersen FSPDB1C – Frequently Asked Questions

1) Can the Mersen FSPDB power distribution block be used on a 1500V DC solar or battery panel?
Yes. The FSPDB is UL rated at 1500 V on both AC and DC, which is what makes it usable on 1500V DC PV and energy storage combiner panels as well as AC distribution. It carries a UL 1059 listing and is rated for 50/60 Hz on the AC side.
2) What wire sizes will the FSPDB block accept on the line and load side?
Primary and secondary are both box-type connectors. The range runs from 350 mcm and 2/0 on the large openings down to #14 to #2 on the smaller ones, with 2 to 8 openings depending on the block size you pick. Box connectors clamp the conductor directly, so no lugs are needed.
3) Does the Mersen FSPDB mount on 35mm DIN rail or does it have to be screwed to a subpanel?
Either. It snaps directly onto standard 35mm DIN rail for the fastest install, and it can also be screw mounted to a back panel where you don't have rail available.
4) Are the FSPDB connectors copper or aluminum, and will they hold up in a humid or industrial enclosure?
The connector body is tin-plated aluminum and the housing is Nylon. The tin plating is the corrosion-resistant surface and is also what lets the connector take aluminum or copper conductors without a dissimilar-metal problem at the contact face.
5) Is the Mersen FSPDB RoHS compliant for a specification that requires it?
Yes, the FSPDB is RoHS compliant, and it is UL 1059 listed as a finger-safe power distribution block. That pair covers most institutional and OEM panel specs that call out both a hazardous-substance restriction and a UL listing for the terminal block.
6) What is this block actually for, splicing or tapping off power?
Both. Typical uses are splicing cables in commercial and industrial panels, splitting one primary feed into several secondary circuits, fixed junction tap-off points, DIN rail control panel wiring, and panelboard or load center distribution. It is a fixed distribution point, not a fused disconnect, so overcurrent protection has to sit ahead of it.
