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.

ote:N Not for use with IQ 35M or IQ MESII.
