MS Series: Split Core Current Transformers (mA Output)

Product Description

Easy to install, ideal for energy mangement applications, as well as revenue metering using Elkor's Power Metering devices.

Unlike the standard 5A CTs, the MS Series Current Transformers do not produce high voltage surge when opened . They generate a low energy mA output and no special protection and/or shorting blocks are required. Maximum open secondary voltage is clamped at about 22 V peak.


  • Ideal for use with Elkor Technologies Inc. Power Meters:
  • Current Transformers for the i-Spy AC Current Transducer.
  • Current Transformers for the i-Snail-X AC Current Transducer.
  • Secondary current transformers applied on 5 A leads of the existing CTs
