Barrier 30
Feed-thru terminal blocks are commonly used in telecom panel power
23
distribution units (PDU’s) and other applications where external power
needs to be transferred to feed a circuit.
Single stud terminals simply provide a single junction point to connect
25
two or more ring type terminals.
Motor terminal blocks are specically intended to be used with electric
26
motor junction boxes to provide delta or wye wiring congurations.
These wiring components are intended to be used for grounding in
27
electrical systems.
These rugged terminal blocks provide protection from direct contact
with live terminals.
These robust style of terminal strips are commonly used in utility
panels to aide in the control of power generation and transmission
equipment.

Barrier terminal strips are the most cost effective means of junctioning
wires in lower power applications. Various hardware accessories are
available to meet circuit requirements.
These terminals are intended for junctioning wires at a single point by
means of a bare wire, prepared wire or hardware (quick-connects).
These terminal blocks are constructed to meet the requirements of Mili-
35
tary Specications A-A-59125 & MIL-T-55164-C, and are only to be used
in applications requiring compliance with these specications.
DIN sectionals provide a compact semi-touch proof construction for a
37
range of wire sizes. These provide end-users the ability to construct
terminals to various line lengths per application.
NEMA sectionals have an open barrier appearance and style in a
39
sectional construction to provide end-users the ability to construct
terminals to various line lengths per application.
