Toroidal solid-core current transformers are more compact and accurate. You must disconnect the measured circuit to install solid core CTs, so they are better suited for new wiring or permanent installation.
- 0.333 Vac output at rated current
- Accuracy ±1% from 10% to 130% of rated current
- No exposed metal
- Phase angle <1 degrees
- UL & CE recognized for voltages up to 600 Vac
- 8 ft. twisted-pair wire, 600 Vac rated
- Qualified under the Buy American provision in the American Recovery and Reinvestment Act of 2009 (ARRA).

- The CT suffix "-yyy" is the rated amps. The "I.D." is the inside diameter of the CT. The "Max. Amps" is the highest continuous current that the CT can handle.
- The "Max Wire Gauge" is the largest wire gauge that should fit through this size of CT.
- * These sizes may or may not fit, depending on the insulation thickness.
