Blackburn PSB6559-1 6-POS. SETSCREW BAR W/MOUNT.HOLES

The PSB6559-1 is a 6-position setscrew bus bar, so it gives you six individual setscrew ports for terminating six conductors on one bar. Each conductor lands in its own port and is clamped by a setscrew rather than crimped, so no crimping tool is needed.

Mounting holes are already provided. The PSB6559-1 is furnished as a 6-position setscrew bar with mounting holes, so it bolts directly to a panel, enclosure back plate, or standoff insulator without field drilling.

The bar body is aluminum. Aluminum-bodied setscrew bus bars of this kind are the standard choice where both aluminum and copper conductors may be landed, which is why they are common on service and feeder neutrals and grounds. Size the conductor to the port rating marked on the bar itself before you land it.

A setscrew bar is the faster install: you strip the conductor, drop it into one of the six ports, and torque the setscrew, with no crimp tool, no dies, and no separate lug per conductor. Compression lugs are the better answer when you need a single high-current termination bolted to equipment, or where the specification calls for irreversible compression connections. For consolidating several grounds or neutrals onto one landing point in a panel or enclosure, the 6-position setscrew bar is the simpler part.

Order Blackburn PSB6559-1. That is the manufacturer part number for the 6-position setscrew bar with mounting holes, and it is the only model on the bar. Give that number to a distributor rather than describing it, since Blackburn builds this style in many position counts and port sizes.

It ships as a single unit. The selling unit of measure is each, so one order quantity gets you one 6-position bar with its setscrews. If you are landing more than six conductors, order multiple bars.

Country of origin is the United States. That matters on public and institutional work where domestic-sourcing language appears in the specification, so it is worth noting on submittals.
