Heavy-duty busbars

Available in a broad range from 3-studs to 8-studs, Pro Installer busbars offer the installer greater flexibility to select busbars to match their load and space requirements. Compact footprints and modular designs allow for space saving and scalability. Robust construction, thicker copper conductors and additional mounting holes provide the basis for secure, reliable, electrical installations.
The covers feature snap-out side skirts providing additional cable entry as required, while the label recess provides the perfect landing for handheld-printer labels. It’s easy linking to other Pro Installer products because of the common interconnection height, and the radiused busbar ends improve cable routing options for large cables.
