Description
The Next Generation Power Distribution Block (PDB). Mersen power distribution blocks provide a safe and easy method of splicing cables, splitting primary power into secondary circuits and fulfilling requirements for fixed junction tap-off points. All blocks are UL and CSA approved while meeting spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code®. PDB options include single or dual conductor primary inputs and up to 30 secondary outputs. Specialty blocks are available allowing for up to 7 primary inputs. The MPDB series is offered in three size categories: miniature (MPDB62 and MPDB63 series), intermediate (MPDB66 and MPDB67 series), and large (MPDB68 and MPDB69 series), in both aluminum and copper.
Features
- Specifically engineered to handle up to 1000V AC/DC, this power distribution block is the ideal solution for high-voltage photovoltaic (PV) arrays and modern industrial energy storage. Utilizing a high-voltage rated component ensures your system remains fully compliant with the latest NEC requirements for renewable energy installations, preventing insulation breakdown and hazardous arcing.
- This integrated 3-pole design allows you to manage three-phase power distribution within a single, compact footprint, significantly reducing the rail space required compared to individual blocks. The streamlined layout simplifies wire management for industrial motor controls and HVAC sequencers, allowing for a cleaner, more organized professional installation that is easier to troubleshoot.
- Featuring versatile pressure-plate terminals that accept wire sizes from #4 down to #14 AWG, this block provides maximum flexibility for both heavy-duty primary feeds and smaller secondary branch circuits. The high-conductivity tin-plated aluminum connectors ensure a low-resistance interface, preventing localized overheating and voltage drops that can degrade the performance of sensitive downstream electronics.
- Designed with an IP20-rated "finger-safe" enclosure, this distribution block prevents accidental contact with live energized parts during routine maintenance or inspection. This built-in safety barrier is a critical upgrade for industrial facility managers aiming to reduce arc flash risks and meet stringent OSHA and NFPA 70E workplace safety mandates without the need for additional custom plexiglass shielding.
