Square D 9080LBA364101 Power Distribution Block 3 Pole

Product Description

The SQUARE D 9080LBA364101 is a three-pole phenolic power distribution block rated for 600 VAC service. It accepts aluminum conductors up to 340 amps and copper conductors up to 420 amps, making it suitable for mixed-conductor panel builds and service equipment. One primary connection feeds one secondary connection per pole, supporting straightforward branch-circuit distribution in electrical enclosures and control panels. The phenolic housing provides strong dielectric resistance in demanding commercial and industrial environments. Licensed electricians install this component during new panel construction or when upgrading existing distribution assemblies to support higher-ampacity loads.

This distribution block is used in commercial electrical panels, motor control centers, switchboards, and large residential service equipment where a compact, high-ampacity termination point is required. Its three-pole configuration covers all phase conductors in a standard three-phase installation. It is also applicable in single-phase high-ampacity circuits where a clean, organized distribution point is needed inside a NEMA-rated enclosure.

Key Features

• Dual conductor rating: 340 amps for aluminum, 420 amps for copper conductors
• Rated for 600 VAC service — covers standard commercial and industrial distribution voltages
• Three-pole design handles all phase conductors in a single component
• Phenolic housing delivers high dielectric strength and thermal resistance
• Meets CE, CSA, RoHS, and UL Listed standards for broad application compliance
• One primary and one secondary connection per pole for clean, organized wiring

Compatibility

Designed as an OEM-style replacement or new-install distribution block for commercial and industrial electrical panels and enclosures requiring a three-pole, 600 VAC rated termination point.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel or enclosure completely before mounting or wiring this block. Verify that conductor gauge and material match the block's rated ampacity for aluminum or copper before terminating. Secure the block to the enclosure using the appropriate mounting hardware for the enclosure type.
