DENT Mini and Midi Hinged current transformers are high-performance hinged current sensors designed for use in energy metering, load survey, demand metering, energy audits, and submetering applications.They are ideal where space is limited, such as when metering multiple loads within an electrical panel. Ferrule CT leads are compatible with ELITEpro Series energy data loggers and PowerScout Series power submeters.

Extending CT Leads

8 foot black & white twisted pair CT leads are standard. CT leads can be extended up to 500 ft by using the same wire type/AWG. Learn more about extending the leads on your current transformers here

The small Mini CTs (HSC) are available in 20A and 50A, while the larger Midi CTs (HMC) are available in 100A and 200A.
