Feature:

*Core material and grades:  Ni、Fe and Mo alloy (abbr:permalloy or nickel iron alloy ,or mumetal alloy)

*Material grades:1J79,1J85

*Core type:  lamination.

*Ultra-high initial permeability, high volt-ampere output.

*high sensity for feeble current ,min.detection current up to 0.1mA

*Low coercive force

*excellent thermal stability ,small error drift for -25-+75℃

 

Application:

1)zero phase current transformers for GFCI,AFCI,ALCI

2) ZCT for Residual current circuit breakers (RCCBs)

3)ZCT for Earth leakage circuit breakers(ELCBs)
