Electrical Current Transformers CR8351

Electrical Current Transformers, CR8351The CR Magnetics CR8351 series electrical current transformers are available in both wire lead and printed circuit board styles. The PCB styles are mountable for automated assembly and feature a non-symmetrical mounting hole pattern to ensure correct orientation.


Core material is a high grade laminated nickel alloy material to provide very low ratio error and phase angle error. The CR8300 series of transformers is designed to meet requirements of IEC 1036 and ANSI C12 for electric metering. They are designed to operate in 50 or 60 Hz systems.
