 Visit the online store page

Large AC Split-Core CTs are in principal the same as the standard sized AC Split-Core CTs but are physically much larger and have a lower accuracy. In most cases, it is better to use a Rope CT instead. For pricing and available models, see the online store.

  • 2" CTs are relatively large at 4.75" x 5" x 1.2", ensure there is enough room in the panel
  • Low end accuracy is poorer than other CT options
  • Special restock fees may apply if returned
  • Lead time may be longer than other CT options
