Split core Current Transformer, Current Sensor 

We  sell several different families 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 ratio outputs) 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.

CTM split core current transformer

The CTM series CTs are optimized for branch circuit monitoring. They have a hinged opening mechanism for easy installation. The small size and low cost is ideal for monitoring many circuits in a panel.
