LZZB9-10A
The LZZBJ9-10A current transformer is primarily designed for indoor power systems with a rated frequency of 50 Hz and a rated voltage of 10 kV or less (with a maximum operating voltage of 12 kV). Its core functions are to accurately measure current and electrical energy in the circuit and to provide reliable signals to relay protection devices. This model is widely used in indoor switchgear—such as center‑mounted switchgear and cubicle switchgear—as well as in complete high‑ and low‑voltage equipment sets.
