The eGauge ECSXX series CTs are split-core current transducers (CTs) with CTid technology. CTs are installed around current carrying conductors to measure amperage as part of a power metering system. Thanks to the split-core design, they are easily retrofitted to existing power systems and do not require the conductors to be disconnected. A 333mV output means no shorting blocks are required. All ECSXX CTs are UL2808 certified.

eGauge CTs use CTid technology for auto-detection and have an onboard LED which can be used to identify which CT is connected to a given sensor port. This is useful if the CT leads cannot be traced.
