Mersen MPDB Series Open-Style Power Distribution Block, Tin-Plated Aluminum

The Mersen MPDB Series is a Next Generation Open-Style Power Distribution Block (PDB) engineered to safely splice cables, split primary power into secondary circuits, and provide fixed junction tap-off points for commercial and industrial power distribution. This block is rated 1000V AC UL and 1000V DC UL, features Box-to-Box connectors on both the primary and secondary sides, and uses Tin-Plated Aluminum conductors housed in a Glass Filled Polycarbonate body for durable, code-compliant performance. The MPDB Series is available in 1-Pole, 2-Pole, and 3-Pole configurations, allowing installers to select the pole count that matches the primary-to-secondary circuit splitting requirements of a given panelboard or enclosure while retaining the same construction, voltage rating, and short circuit performance across every option.

Key Features

  • Pole Configuration: Available in 1, 2, or 3-pole versions to match primary-to-secondary circuit splitting needs.
  • Durable Construction: Tin-Plated Aluminum connectors resist corrosion while maintaining reliable conductivity.
  • Box-to-Box Connections: Box connector type on both the primary and secondary sides for secure cable splicing.
  • Insulating Body: Glass Filled Polycarbonate housing provides electrical insulation and mechanical strength.
  • Voltage Rating: 1000V AC UL and 1000V DC UL for demanding power distribution applications.
  • Short Circuit Protection: Rated 100 kA with a 60A fuse (Class G), 100 kA with a 30A fuse (Class CC), and 10 kA standalone.
  • AC/DC Versatility: Suitable for AC or DC circuits at 50/60 Hz.
  • Direct Screw Mount: Simplifies installation into panelboards and enclosures.

Mersen MPDB67561 – Frequently Asked Questions

1) Can a Mersen MPDB power distribution block be used on a 1000V DC solar or battery circuit?
Yes. The MPDB Series is rated 1000V AC UL and 1000V DC UL, and it is listed for AC or DC service at 50/60 Hz, so it works on DC strings as well as AC feeders.
2) How many poles do the Mersen MPDB blocks come in?
Three pole counts are offered: 1-pole (MPDB67561), 2-pole (MPDB69132), and 3-pole (MPDB67053). Pick the 3-pole for a three-phase feeder tap, the 1-pole where you only need to split a single conductor such as a DC positive or a neutral.
3) What short circuit current rating do I list on my UL508A panel label for this Mersen block?
It depends on the upstream protection. The MPDB block carries 100 kA when protected by a 60A Class G fuse, 100 kA with a 30A Class CC fuse, and 10 kA standalone with no fuse ahead of it. If your panel needs a 100 kA SCCR, you have to feed the block through one of those fuse classes and amp ratings.
4) Is an open-style power distribution block allowed inside a UL508A industrial control panel?
The MPDB Series is UL and CSA approved and meets UL508A along with National Electrical Code spacing requirements for feeder and branch circuits, which is why it is used for panelboard and enclosure wiring. Open-style means the terminations are exposed, so it belongs inside an enclosure or behind a barrier, not in an accessible location.
5) Can I land copper conductors in a tin-plated aluminum distribution block?
The MPDB uses tin-plated aluminum connectors, which is the standard dual-rated construction for power distribution blocks; the tin plating is what resists the corrosion and oxidation you get at an aluminum-to-copper interface. Terminations on both the primary and secondary sides are box connectors, so conductors are clamped under a pressure screw rather than lugged.
6) How does the Mersen MPDB mount in an enclosure, and do I need a DIN rail?
No rail needed. The MPDB is a direct screw mount block, so it fastens straight to the enclosure subpanel or backplate with screws. Plan your subpanel hole pattern accordingly if you are replacing a rail-mounted block.
7) Can I use a power distribution block instead of splice connectors to tap a feeder into branch circuits?
That is exactly what the MPDB is for: splicing cables, splitting primary power into secondary circuits, and giving you fixed junction tap-off points for feeder and branch circuit work. Unlike a taped or crimped splice, each tap is a re-openable box terminal you can inspect and re-torque.
8) Will the plastic housing on this distribution block hold up to heat and impact in an industrial panel?
The body is glass filled polycarbonate, chosen for both electrical insulation and mechanical strength, and the block is RoHS compliant. Glass fill is what keeps the barriers from deforming under conductor pressure and panel heat.
