The CSBL125B is a 125 A splitter block from the CSBL Series, described by the manufacturer as the 125 A box version. CSBL blocks are used in Hammond standard splitter troughs and boxes, so this part suits electricians replacing, adding or fitting blocks in a splitter box installation.

Each CSBL block includes a main lug and branch lugs. On the CSBL125B the main lug is rated 125 A and accepts wire from 2/0 down to 14 (max./min.). The branch lug ampacity is listed as 3/70, with a wire capacity of 3 x (2/0-14), so three branch conductors in the 2/0 to 14 range can be terminated.

The block is built from Cu-Al monopiece connectors secured to insulators, and both main and branch lugs can use either copper or aluminum conductors. All CSBL blocks are rated 600 V, and 75 °C conductor ampacity is permitted.
