Continental Control Systems sells several different series of current transformers (CTs) in various window sizes, current ranges, and accuracy grades. All of the CTs that we sell feature safe, low-voltage outputs (not current output ratio CTs) for indoor use only in 50 or 60 Hz circuits up to 600 Vac. This type of CT contains a built-in burden resistor and is calibrated to output exactly 333.33 mVac when the CT’s rated full-scale current flows through the conductor in the CT’s window opening.
To select a CT, we recommend first deciding on a style, either an opening (split-core) or a solid-core CT, then select the model you need based on the maximum load current you are measuring and the size of the conductor being monitored.
