Zero Sequence Current Transformer Cores

Applications:

• Earth leakage current breaker

Characteristics:
     • High permeability, low coercive force, low core loss 
     • Sensitive to micro-leakage-circuit, excellent endurance against strong current impact 
     • Advanced core-surface-protect technology, proof against crumbs 
     • Profound temperature stability, working well between -25℃ and 100, Uavg(100°C/-25°C)/ Uavg(20°C)=0.7～1.2
