Applications requiring 5A Current Transformer outputs require the

use of the CS005 Class 10 Current Sensor as an interposing sen

sor which reduces the input to the meter module to <10ma .  ANSI

C12 .20 class 0 .5% accuracies may be achieved using either the

Eaton CSXXX 10 mA or PXMP-CSXXX 100 mA current sensors and

direct voltage metering .  Interposing Potential and current transform

ers may introduce additional error .

The PXMP Meter supports a variety of current sensors .  Eaton offers

some sensors specially designed for use with our products .  We also

support the use of industry standard current sensors .  When specify

ing current sensors, in general, note that:

• Solid core sensors tend to have higher accuracy than split core

designs .

• Split core sensors are often installed in Retrofit applications where

it is not practical to disconnect the load conductors in order to

mount a solid core sensor .

• Current loop output sensors tend to have accuracy and noise

immunity advantages over 333 mV output sensors .

• 333 mV sensors are very useful since they eliminate open circuit

risks and are available in a wide range of primary current ratings .

• Eaton’s CS005 enables the PXMP Meter to interface to standard

5 A current transformers, either split core or solid core .
