The CSBL600 is the 600 A splitter block in the CSBL Series. CSBL blocks are used in Hammond standard splitter troughs and boxes, and this part fits electricians handling 600 A class feeders who need to fit or replace a block in a splitter enclosure.
The main lug is rated 600 A and is sized for paralleled conductors: two conductors of 600MCM - 4, or four conductors of 250MCM - 1/0. Branch lug ampacity is listed as 6/200, and branch wire capacity is 6 x (3/0-14), so six branch conductors from 3/0 to 14 can be terminated.
Each block includes a main lug and branch lugs made from Cu-Al monopiece connectors secured to insulators, and both main and branch lugs can use copper or aluminum conductors. All CSBL blocks are rated 600 V, and 75 °C conductor ampacity is permitted.
The CSBL600 is REACH and RoHS compliant. It ships in a bag with a shipping weight of 1 lbs (0.45 kg); UPC 623980263854.
