Product Description

The 5AS by Sentran Corporation is a UL Listed current transformer that can take an input from 50A to 6000A and output a corresponding 5A or 1A output.

The 5AS instrument current transformer is available in many different window sizes.  See the chart on the tab All Available Window Sizes for a full list of options.  The CTs in the drop-down are common sizes (that are often stocked).  This UL Listed current transformer incorporates internal  transient voltage suppressors (TVS) for shock protection in case the output leads are not terminated.

The output is linear from 10% to 100% of range with a ratio accuracy of +/- 0.5% full scale, depending on burden value.  The 5AS is UL Listed under UL2808 and IEC61010-1.

Additional Configuration Options (may increase lead time):

  • Accuracy can be adjusted to +/-0.5% full scale when known burden value is provided by customer
  • Relay protection is available up to C800 sizes.
  • Voltage withstands are available for up to 4700 Vac.

Compatible power meters accept an amperage input.  Look for meters on our website that start with this symbol:
