Square D 9080LBA163104 Distribution Block 1P 335A

Product Description

The SQUARE D 9080LBA163104 is a single-pole phenolic power distribution block rated for up to 335 amps with copper conductors or 270 amps with aluminum conductors at 600 VAC. It features one primary connection and four secondary connections, making it a practical solution for branching a single feed into multiple circuit outputs within a panel or enclosure. The phenolic housing provides durable electrical insulation suitable for industrial and commercial power distribution applications. Licensed electricians install this block during panel builds, retrofit projects, and load-center expansions where organized conductor termination is required.

This distribution block is suited for use in commercial and industrial electrical enclosures, control panels, and power distribution assemblies. It handles both aluminum and copper conductors, giving installers flexibility when working with mixed wiring infrastructure. The single primary input with four secondary outputs supports common branch distribution layouts where space and conductor organization are a priority. It is appropriate for new installations and direct replacement applications in existing switchgear and panel assemblies.

Key Features

• 335-amp rating with copper conductors, 270-amp rating with aluminum conductors
• 600 VAC voltage rating for commercial and industrial circuits
• 1 primary connection and 4 secondary connections for efficient branch distribution
• Phenolic housing for reliable electrical insulation and durability
• Certified to CE, CSA, RoHS, and UL Listed standards

Compatibility

Designed as an OEM-style replacement distribution block for single-pole power distribution applications in commercial and industrial electrical enclosures rated up to 600 VAC.

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 before beginning work. Verify conductor type and size against the appropriate ampacity rating — copper at 335 amps or aluminum at 270 amps — before terminating. Secure the block firmly to the enclosure mounting surface and confirm all terminations are tight before re-energizing.
