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.
ACT Split core current transformer
The Accu-CT revenue grade, split-core current transformer offers outstanding linearity and very low phase angle error with easy one-handed opening and closing, even wearing gloves.
CTL Split core current transformer
The CTL series revenue grade, split-core current transformer offers excellent linearity and very low phase angle error with one-handed opening and closing, even wearing gloves.
The CTL CTs are only available with Option C0.6 indicating that they meet IEEE C57.13 class 0.6 accuracy standards.
CTB Split core current transformer
The CTB series CTs are designed for higher currents (up to 6000 amps) and larger conductors, including bus bars. They are available in a wider range of shapes and sizes including five stock models and almost unlimited custom variations. They have a removable section, so that they can be installed without interrupting the circuit.
CTRC Rogowski coil current transformer
The CTRC Rogowski coil current transformers are accurate, flexible, rope-like current sensors that can be connected around conductors. They greatly simplify AC current measurements of conductors where traditional split-core and solid-core CTs are difficult to use. With its flexible design, the CTRC is perfect for large bus bars and irregular-shaped conductor bundles. In addition, the coil’s small profile allows it to fit into tight spaces where rigid CTs won’t fit.
CTT Solid core current transformer
The CTT series toroidal (solid-core) current transformers do not have an opening section, so you must disconnect the measured circuit to install solid core CTs. They are better suited for new wiring or permanent installation.
