Accurate current measurement is essential for effective electrical system monitoring and protection. At Blackhawk Supply, we stock a comprehensive range of current transformers (CTs) engineered to step down high electrical currents into manageable signals for metering, protective relaying and control applications.

From split core current transformers that install without circuit interruption to solid core models delivering precision measurement, our CT inventory supports the diverse requirements of industrial facilities, commercial buildings and renewable energy installations.
