Notes
*The current transformer is allowed to be connected to an AC circuit not exceeding 0.66kv, and the long-term working current not exceed 1.1 times the rated value, and 1.2 times the rated current is allowed to be used for a short time, and the working time does not exceed 1 hour, except for non-standard and protection.
*When the measuring instrument is connected to S1 and S2 terminals, it must to be noted that the total impedance (including wiring) of the connected instrument does not exceed the rated load of the current transformer.
*It is strictly forbidden to open the secondary circuit of the current transformer during operation. If the secondary coil is open circuit when it is powered o accidentally , demagnetization must be carried out to reduce the increase of error.
*The current transformer is only used in places without direct invasion of rain and snow,no serious pollution ,no severe vibration ,no corrosive metal and dust or steam damaging insulation.
Advantage
*High quality oriented and low loss steel to ensure the accuracy of products;
*Pure copper winding, uniform winding and stable performance;
*ABS / PC flame retardant material, high temperature resistance, size stability;
*Top cover anti-theft electric design, can be confident to add lead seal, ensure safety.
