Setra Split Core Data sheet
Split Core Performance CT
Current Transformers
DESCRIPTION
The hinged Split Core Performance CTs are small, low cost current transformers
with high accuracy over a wide dynamic range with excellent phase shift. These
CTs are ideal where space is limited such as when metering multiple loads within
a panel board. Use for current measurement, energy metering, load surveys, demand metering, energy research, and sub-metering.
