Mersen MPDB63101 Power Distribution Block 85A 1P 14-4 AWG 600VAC/DC

SKU CH-DYW8-N1KMG

Single-pole block rated 85 A at 600 V AC/DC with 14-4 AWG terminals, UL 1953 and CSA 6228-01 listed

  • Engine BrandMERSEN
  • Handles up to 85 A for high-current circuits
  • Single-pole design simplifies one-phase wiring
  • Accepts 14 to 4 AWG conductors on both sides
  • Rated 600 V AC/DC for industrial voltage levels
  • UL 1953 and CSA 6228-01 listed for code compliance

85 A Single-Pole Distribution Block

The Mersen MPDB63101 is a single-pole power distribution block rated for 85 amperes at up to 600 VAC or VDC. It accepts one primary and one secondary conductor per pole, each in the 14 to 4 AWG range, making it suitable for panel builders and electricians consolidating feeds in industrial control cabinets or generator hook-ups. The open design allows visual inspection of connections during installation and maintenance.

14 to 4 AWG Capacity With 85 A Headroom

The block handles conductors from 14 AWG up to 4 AWG on both the line and load sides, giving ample room for typical branch-circuit wiring while staying within the 85 A continuous rating. Voltage is rated at 600 VAC/DC, so it covers standard North American three-phase and single-phase service voltages. The single-pole layout limits use to one phase or DC bus per unit, so multi-phase distribution requires additional blocks mounted side by side.

Compact 3.08 by 2.81 by 1.05 Inch Footprint

Measuring 3.08 inches long, 2.81 inches deep and 1.05 inches wide, the block fits into tight panel spaces without demanding special mounting hardware beyond standard DIN rail or screw mounting. It carries UL 1953 and CSA Class 6228-01 listings, confirming compliance for factory-wired equipment. The open construction frees up wiring room around terminals but offers no integrated barrier or cover, so installers must provide their own insulation or guarding where required by local code.

Questions about this item

Will the single-pole 85 A block accept the same 14-4 AWG cables I already use on my existing busbars?

Yes, both the primary and secondary connections on this block accept 14 to 4 AWG conductors, matching the wire range you currently run.

How can I verify the block is carrying its rated 85 A at 600 VAC/DC after installation?

Measure the voltage drop across each pole under load; a low millivolt reading consistent with the 85 A rating confirms proper contact and no overheating.

Does the MPDB63101 ship with mounting hardware or only the open-design block itself?

The package contains the power distribution block only; mounting screws, DIN rail clips or busbar lugs must be sourced separately.
