63mm Toroidal Current Transformer, 600V
The CTT series of toroidal, solid core current transformers provide highly accurate, non-contact step-down transformation of the AC primary current to a level appropriate for micro-processor based circuits. These solid core current transformers feature high over current measurement capability over a broad frequency range under harsh environmental operating conditions.
