What It Is: TE Buchanan 1604797-1 Battery Stud Terminal Block
It is a panel-mount, single-level block designed for high-current battery and power distribution connections, using a stud termination style.
The terminal width of 94.0mm sets the panel cutout and the spacing between the two studs — this is the dimension to match against your battery post or busbar layout. With 2 positions, this block handles a single positive/negative cable pair. The stud termination accepts ring terminals or direct cable lugs; the panel mount keeps the block fixed in the enclosure.
