Technical specifications and ordering information for Fuji Electric CC3L through-type current transformers.
The CC3L series are round‑hole through‑type current transformers with a double‑mold structure that provides excellent moisture resistance and good insulation. They offer selectable secondary currents of 5 A or 1 A, accuracy class 1.0, and can be adapted by changing the number of primary winding turns.
Three types are available with rated burdens of 5 VA, 15 VA, and 40 VA. The mounting base rotates up to 90° for flexible installation, and the transformers support primary currents from 60 A to 750 A.
