The Micro 19 range of split core CT’s are amongst the smallest available standard 5Amp secondary metering CT’s. ID is 19mm, suitable for most 100 and 200 Amp supplies. The 13mm outside dimensions of the CT clamp allows for easy fitting in the close space between phase conductors as they spread into the DB busbar terminations. Class 1 performance makes these CT’s ideal for MID metering applications. CT ratio is 100:5A. This product is the MICRO191005-L.
