Leakage Current Protection Switch Transformer Nanocrystalline Magnetic Core (SYL)

Performance characteristics

High permeability, low coercivity, low loss
It has excellent resistance to high-current surges, ensuring stable tripping current.
The permeability adjustment range is wide, enabling detection of various waveforms and different levels of leakage current.
Excellent temperature stability allows for stable operation between -25℃ and 100℃.
Uavg(100℃/-25℃) / Uavg(20℃) = 0.7–1.2
