1323580 - 175A Power Distribution Block

1323580 - 175A Power Distribution Block

There’s a point in every panel build where you need to stop stacking wires and actually organize the power. That’s where the Marathon 1323580 comes in. It gives you a clean way to bring in a main line and split it out to multiple circuits without turning the panel into a headache later. This is a 175 amp, 600 volt, 3-pole distribution block, so it’s meant for serious loads—not light-duty fixes. It accepts both copper and aluminum wire, which makes life easier when you’re working with mixed materials or upgrading older systems. Once everything is landed, the connections feel solid and stay that way. The build is straightforward and dependable. The thermoplastic base holds up well in high-heat environments, and the tin-plated aluminum connectors help keep conductivity consistent over time. It’s also compact enough that you’re not sacrificing space just to get proper distribution. In short, it does exactly what you need it to do—split power cleanly, hold connections tight, and stay out of your way.
