Stud blocks
Catalog number example:
16280-3 is a 3-pole 16280
Where:
•
The prefix “16280” defines the block’s lineside
characteristics (i.e., one conductor port per pole
that accepts 2/0 - #14 Cu/Al conductors) and the
loadside characteristics (i.e., 1/4-20 x 3/4” stud).
•
The suffix “3” in this example defines this as a
three-pole block.
•
See the catalog number tables for details on the
available lineside/loadside characteristics.
How to order:
From the catalog number tables, select the catalog
number that defines the desired lineside/loadside
port and conductor characteristics.
Catalog symbols:
•
162__-(poles)

Description:
Eaton’s Bussmann™ series port-to-stud and studto-stud power terminal blocks are available with
current ratings up to 760 A.
The stud connection is convenient for lug/ring wire
terminals and allows for easy field wiring.
These blocks are UL® Recognized to UL 1059 and
rated for use in UL 508A industrial control panels.
These blocks are factory configured from 1- to
3-poles (catalog number dependent) with optional
covers available (order covers separately).
Add to the catalog number the suffix that defines
the desired pole configuration. Note, you must
select from the available number of poles for
each catalog number. These appear in the second
column of the catalog number tables.

* 75°C wire (higher temperature rated wire acceptable with appropriate derating). Using a ferrule on a stranded conductor requires a correctly sized UL Listed ferrule
(customer supplied) applied according to the manufacturer’s specifications. Ferrule ratings apply to copper wire only.
** Not covered by CSA certification.
† See table on next page for the tested upstream overcurrent protective devices necessary for achieving this SCCR.
†† Configuration includes washers and hex nuts for each stud.

Ferrule terminal application
•
Rated for dual wire port application to increase the possible number
of lineside and loadside connections. E.g., 16280-1 can accept two
wires into the lineside port (#4 - #8 Cu/Al, #10 - #14 Cu).
•
Bussmann series stud blocks are rated for use with UL Listed
ferrules (see catalog number table for details). Ferrule ratings
apply to copper wire only.
•
Dual wire applications are only viable when using two wires of
the same size, stranding, and insulating and conductor material in
the same port.
•
Ferrule applications allow for the use of a broader range of
conductor stranding and simulate a more efficient, solid wire
connection with the terminal port.
•
Always use UL Listed ferrules in accordance with the
manufacturer’s specifications and instructions.
