Series C7021
Power Feed Thru Terminal Block
Single & Double Row
Filtered Connectors
MAGNUM
®
is pleased to introduce a UL and CUL recognized,
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.
