Magnetic Core of Protection Switch

Protection switch uses zero phase current transformer core as the transducer to drive the work of release, so earth leakage protection is achieved. The zero phase current transformer is made of Fe-based nanocrystalline. Depending on the technical requirements, our magnetic core can be divided into 3 types which are domestic type, industrial type, and high sensitivity type.



Technical Parameters
Domestic Core

Model Size (mm) Input Current (mA) Output Voltage (mV)
HX-NC Φ14/19×6.5 50 ≥1.80
HX-NC Φ19/25×10 50 ≥3.0
HX-NC Φ13/17×6.5 50 ≥1.20
HX-NC Φ20/25×10 50 ≥2.0
HX-NC Φ15/22×10 50 ≥2.5

Industrial Core

Model Size (mm) Input Current (mA) Output Voltage (mV)
HX-NC Φ18/28×15 100 ≥9.0
HX-NC Φ23/33×15 100 ≥9.0
HX-NC Φ55/65×10 100 ≥2.5

High Sensitivity Core

Model Size (mm) Input Current (mA) Output Voltage (mV)
HX-NC Φ8/12×4.5 50 ≥0.6
HX-NC Φ10/14×4.5 50 ≥0.65
HX-NC Φ13/17×6.5 50 ≥1.2
HX-NC Φ9.6/13.4×10 50 ≥0.7

Note:
1. Testing conditions for all: f=50Hz, N1=N2=1.
2. Other specifications are available upon customer's request.

Earth leakage circuit breaker is suitable for low voltage power system, and it can prevent direct and indirect electric shocks. It has high sensitivity, and can cut off power supply effectively to keep human safe which makes it widely applied. We can provide magnetic core of protection switch with various specifications. Our product features excellent soft magnetic properties, and the saturation magnetic flux density is as large as 1.2T. The core loss and soft magnetic properties under high frequency are similar to Co-based amorphous metal, but our product is cheaper.

Huaxin is a specialized magnetic core of protection switch manufacturer and supplier, based in China. In addition to amorphous / nanocrystalline core, we also offer silicon steel core, amorphous metal, transformer, and more.
