The CR Magnetics line of Instrumentation Grade Electrical
Current Transformers are available in either Commercial or
ANSI Metering Class. The Commercial Class transformers
are lower cost and well-suited for current monitoring appli-
cations. The ANSI Metering Class transformers are higher-
cost units intended for power monitoring applications
where high accuracy and minimum phase angle error are
required. Twelve different window openings and eight dif-
ferent mounting styles along with numerous secondary
ratios are available to meet most applications. This short
form catalog shows an overview of our most popular 5
amp secondary transformers. Contact factory for different
sizes or unique electrical requirements.
