Microcrystalline magnetic ring coil
The characteristics of making the core of leakage protection switch with Fe based nanocrystalline alloy
1. Low coercive force, high initial permeability -- can reduce the action current of leakage switch
2. The saturation magnetic induction intensity is higher than permalloy
3. High permeability -- greatly improve the accuracy of transformer and reduce the ratio difference
4. Light weight and low cost -- the price is obviously superior to permalloy
5. It has good anti overload ability and good temperature stability -- it can work for a long time at 55-130 ℃
