power feed through terminal block. The C7021 Series block

has rows of two 1/4-20 studs which are capable of accom-

modating the industry standard two-hole compression lugs on

5/8" centers. The block is rated at 300V and 175A when using

both studs in parallel or 115A using a single stud per line.

The C7021 is manufactured using a durable UL 94V-0 ther-

moplastic in order to minimize barrier breakage. The block

can be mounted using four #6 thread cutting screws that

mount from the backside or using the optional mount ends

to secure the block to the panel from the front. Additional

hardware and optional dead-front covers (Part No.

CSB7021-XX) are also available.

APPLICATIONS

The C7021 terminal block is intended for use in applications

requiring up to 175A utilizing a 2-hole compression lug on

5/8" centers. It is ideal for use as an input/output block for

telecommunications power panels, or anywhere in which

-eliminating busbars would be an advantage.
