Current Transformers — CTs (Bulletin 1411)

Allen-Bradley offers a full line of low voltage Current Transformers (CTs) for various power measurement devices and applications. Power measurement devices include protective relays, analog devices, transducers and powermonitors. The purpose of CTs is to scale high currents to more manageable levels while preserving a reasonable level of accuracy. CTs typically scale the current flowing through their primaries to 5 amps (full scale) on their secondaries. The majority of power measurement devices are designed to accept this current level.
