 RCT Series Current Transformer

RCT range of current transformers can be applied to test,control,display and record the running of the electrical

equipment,and to protect the equipment against the damage,in the AC circuit with the rated voltage value below 720V and the

frequency of 50-60Hz.The product can be also applied to form a complete set of mine transformer. RCT have larger capacity.

With the method of fixed installation.
