Zero Phase Current Transformer

  • 10A Zero Phase Current Transformer The 10A zero phase current transformer is applied to small current monitored circuit. When the monitored circuit fails, it can turn 10A input current into zero phase current ranging from 10mA to 1,000mA and control the switching of circuits. It has high sensitivity and ...
  • 200A Zero Phase Current Transformer The 200A zero phase current transformer can endure input current ranging from 50A to 100A. If the monitored circuit malfunctions, it can output zero phase current which is 500 times smaller than the input current with the suggested 500 turns ratio so that the power supply is cut off to protect the electric equipment...
  • 1000A Zero Phase Current Transformer The 1,000A zero phase current transformer can endure system current ranging from 800A to 1,000A which is the largest among this series. With suggested 1,000 turns ratio, the zero phase current generated is 1,000 times smaller than the system current ...

The zero phase current transformer is mainly used to test electrical lines. The input shall be connected with the circuit being tested. When the tested circuit functions well, the output will have no passing current, but when the circuit malfunctions, induction current will be generated in the zero phase current transformer so that the control circuit is activated to switch power supplies to protect devices.

Due to the excellent mechanical properties, this product is safe and reliable in severe environment. The working temperature ranges from -25℃ to 55℃, relative humidity is less than 90%, and atmospheric pressure ranges from 860mbar to 1,060mbar. This zero phase current transformer is also widely applicable. It can convert 50Hz or 60Hz AC.

This product is designed as a simple structure so that it can respond quickly to malfunctions. It is sensitive and accurate in low current and low magnetic field circumstance, and the action accuracy is better than those of other protective devices. The accuracy is ensured by XF20-6B AC/DC instrumental calibrator. There are several models for monitoring of different circuits with various currents. This RoHS certificated product has 3kV/1mA dielectric strength.

Jiangyin Spark is a China-based zero phase current transformer manufacturer and supplier. We provide a broad range of products including mini clip-on split core current sensor, high frequency transformer, PCB current transformer, and more.

Other Products
  • 400A Protection Current Transformer The 400A protection current transformer has a relatively small input current value. The two different models can respectively turn 200A input current and 400A input current into 100mA small current output so that the circuit is cut off to protect the whole system...
  • 600A Protection Current Transformer The 600A protection current transformer can endure at most 8 times overload. It has wide current measuring range and high consistency. Customers can choose from the black models and the white models...
