UL BUSBAR SUPPORT
Holds the rigid copper busbars that span the enclosure width or
height in place. Systems can be mounted either horizontally or
vertically. These supports provide critical bracing against the
forces exerted upon the busbar structure in the event of a short
circuit condition. While typically mounted to the backpanel of the
enclosure, these supports can also be mounted on the frame or
support structure of a modular PROLINE™ enclosure system.
Each support can be adjusted to accommodate all six rectangular
standard sizes of rigid copper busbar.
