Description
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
- 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
- Safe, low-voltage 0.333 Vac output at rated current for indoor use only in 50 or 60 Hz electrical services
- Accuracy ±1% from 10% to 130% of rated current
- No exposed metal, 600 Vac rated
- Phase angle less than 1 degree
- UL recognized (E969227), CE mark, RoHS
- Twisted-pair, 22 AWG twisted wire leads, 8 feet long
- Qualified under the Buy American provision in the American Recovery and Reinvestment Act of 2009 (ARRA).
