Current Transformer, 30/5A, 75/5A, 100/5A to 400/5A

Current transformer is one of important devices for power system and used to transform the voltage or current. Current radio 50:5A, 100:5A, 250:5A, to 400:5A. AC current transformer with rated frequency 50Hz or 60Hz, free shipping and good value for money.

Note: The installation method of current transformer can be fixed by busbar and fixed by the bottom plate, suitable for installation in any direction. The primary conductor can be busbar or cable.

Specification:

Tips: What causes the current transformer to burn out?

• Secondary open circuit of the current transformer produces high voltage to burn out the current transformer.
• Long-term use of the current transformer makes the insulation aging, local breakdown or discharge occurs and overvoltage is thereof produced, thus burning out the current transformer.
• Long-term overload operation makes the current transformer to give out heat, it is thereof burned out.
• The aluminum contact surface of current transformer’s primary connection is seriously oxidized, which results in large contact resistance. The contact resistance gives out heats and burns out the current transformer.
