Eaton Specification Sheet - PRL2X3400X42CS
The PRL2X3400X42CS panelboard ships with a 400A amperage rating, 42 circuits, and copper bus, delivering low electrical resistance and excellent heat dissipation under load. This combination supports robust fault current paths and cleaner conductor terminations, reducing contact resistance over the life of the installation. Field engineers gain flexibility to stagger feeders and reduce panel crowding, while maintenance teams benefit from consistent torque and fewer creeping connections. In practice, this means fewer outages and a more predictable distribution backbone for critical loads. Copper bus also contributes to longevity in demanding industrial environments, reducing routine maintenance and spare parts needs. The interior design helps with straightforward wiring practices, short training times, and easy integration into existing Eaton-powered distribution ecosystems. The result is a reliable, scalable solution that supports plant uptime and reduces lifecycle costs.
