CTT Solid-Core CT
$38.00 – $55.00
The CTT series toroidal (solid-core) current transformers do not have an opening section, so you must disconnect the measured circuit to install solid core CTs. They are better suited for new wiring or permanent installation.
Toroidal solid-core (donut) current transformers are more compact and accurate than traditional split-core CTs. Solid-core CTs are use by electric utilities for billing. (Note: the low-end accuracy of CCS’ patented Accu-CT split-core technology is better than solid-core CTs)
You must disconnect the measured circuit to install solid core CTs, so they are better suited for new wiring or permanent installation.
