142 Series Finger-Safe Power Distribution Block (1423122)

Part number 1423122 belongs to the 142 Series of power distribution and stud blocks from Marathon Special Products, a Regal Rexnord brand. Distributor data list it as a three-pole power stud block rated 600 V AC with one line and one load connection per pole, using threaded studs (listed as 1/4-20 by 5/8 inch) for ring-terminal lugs, and approximately 200 A per pole. It is panel mounted on an insulating base and carries UL, CSA and CE marks. The block itself is not finger safe; a separate three-pole protective cover (CC1423) is sold for the 142 Series to shield the live studs. Stud blocks of this kind are used to join or tap heavy power conductors inside control panels, motor control centres, generator sets and HVAC equipment where lugged cable connections are preferred to box clamps.
