Current Transformers
General Description
Eaton’s low voltage current transformers are
available in both solid core and split core designs.
Engineered for electronic metering applications,
all solid core designs and selected split core
designs offer ANSI metering quality accuracy.
The current transformer offering has a 5A
secondary at the rated primary current.
Split core CTs are specifically designed to be
installed around primary conductors without
disconnecting wires or breaking the circuit to be
monitored. These current transformers are perfect
solutions for energy management applications and
are manufactured for installation ease.
Application Description
For new construction and retrofit applications
where no current transformer exists, Eaton offers
a complete selection of low voltage (up to 600V)
current transformers. These current transformers
can be used in commercial grade applications such
as control panels and panelboards. Additionally,
they can be used for most industrial metering
applications in switchboards, switchgear and
motor control centers.
