ETCR EM015KM-030KM-050KM-065KM

Split-Core High-Precision Leakage Current Sensor

The ETCR-KM Series Split-Core High-Precision Leakage Current Sensor are designed for the high-accuracy detection of AC leakage current, high-order harmonic current, phase, electric energy, power, power factor, and more. Utilizing advanced CT technology and a split-core structural design, they enable non-contact measurement without the need to disconnect the circuit under test, ensuring safety and speed. They can be connected to phase detection analyzers, industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, high-precision digital multimeters, and other equipment. They are widely suitable for power, telecommunications, meteorology, railways, oil fields, construction, metrology, scientific research and educational institutions, industrial and mining enterprises, and more.

Product Features

Split-Core Non-Contact Measurement Structure

No power outage or disconnection of the measured circuit is required. Portable and especially suitable for on-site online testing. Non-contact measurement is convenient, fast, safe, and reliable.
