Description — Stacking bridges are used with Style C, F, and H rail-mounted terminal blocks. They are designed to save panel space and increase terminal accessibility. Stacking bridge kits allow stacking of up to four terminal block strips. A stacking bridge consists of mounting feet, side plate extensions, and 12 in. or 18. in bridges.
Note:Rigid mounting rail is attached to the bridge. Five kits are available to custom build stacking bridges as listed in the above table. Fuse blocks, disconnect blocks, large Style C terminal blocks (Cat. No. 1492-CE2) and circuit breakers should only be mounted on the upper-most bridge of any assembly.
Ordering Example — A typical ordering example for a Two-Level 18 in. Stacking Bridge is as follows:
Both 12 in. and 18 in. stacking bridges are built in this manner with up to four levels maximum.
