Square D 9080LBC363101 Power Distribution Block 255A 3P

Product Description

The SQUARE D 9080LBC363101 is a 3-pole phenolic power distribution block rated for 255 amps (copper) at 600 VAC. It is designed to split a single power source into multiple branch circuits within a panel, enclosure, or electrical distribution assembly. The phenolic housing provides solid insulation and resistance to heat and tracking, making it appropriate for industrial and commercial electrical installations. Licensed electricians install this component during panel builds, load center retrofits, and branch circuit distribution work where a compact, code-compliant blocking solution is required.

This distribution block is suited for use in commercial and industrial electrical panels, motor control centers, and enclosed distribution assemblies. Its 3-pole configuration handles three-phase or multi-conductor applications. With one primary connection and one secondary connection per pole, it serves straightforward distribution tasks where a single feed needs to be terminated and distributed cleanly within an enclosure. It is appropriate for new construction wiring and retrofit installations requiring a UL Listed distribution component.

Key Features

• 255-amp copper conductor rating supports high-current branch circuit distribution
• 600 VAC voltage rating covers standard commercial and industrial supply voltages
• 3-pole design handles three-phase and multi-conductor wiring configurations
• Phenolic housing provides electrical insulation and thermal resistance
• UL Listed, CSA certified, CE marked, and RoHS compliant
• Compact footprint at 5.4 inches long by 4.4 inches wide by 3 inches tall for enclosure-friendly installation

Compatibility

Designed as an OEM-style replacement and standard-fit power distribution block for commercial and industrial electrical enclosures, motor control centers, and panel assemblies requiring a 3-pole, 255-amp, 600 VAC distribution component.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel or enclosure fully before installing or replacing a distribution block. Verify conductor sizing and torque connections per the manufacturer instructions included with the unit. Do not exceed the rated amperage or voltage when selecting conductors and protective devices for the circuit.
