Current Transformers

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 0.333 Vac 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 a split-core (opening ) or a solid-core (non-opening) CT, then select the model you need based on the maximum load current you are measuring and the size of the conductor being measured.
