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

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.
