1.Features:

 ETCR080A Large Caliber Clamp Leakage Current / Current Sensor

 is well designed and manufactured for measurement of AC current, higher harmonic current, phase, electric energy, power and power factor, by adopting the latest CT technology. Its large caliber 80mm×80mm can clamp electric cable of Φ80mm, or 96mm×4mm flat cable and steel earth wires. It is portable, clamp designed, no need to disconnect the circuit, non-contact measurement, which means safer and faster. It can be connected with phase detection analyzer, industrial control equipment, data recorder, oscilloscope, electric power quality analyzer, high precision multi-meter, widely applied in those fields as electricity, communications, meteorology, railroad, oilfield, construction, measurement, scientific & research teaching institutes, industrial and mining establishments.
