Feature:1. The open close high accuracy current transformer is suitable for the detection of AC leakage current, high order harmonic current, phase, electric energy, power factor, etc.2. Using new CT technology, no need to disconnect the line under test, non contact measurement, accurate measurement, safe and fast.3. The iron core is made ofpermalloy and double layer shielding technology is adopted, so the influence of the external magnetic field is very small.4. This product is easy to operate and easy to carry, ensuring high stability and reliability for year round uninterrupted measurement.5. It can be connected to phase detection analyzers, industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, high accuracy digital multimeters, etc.Specification:Item Type: Leakage Current SensorModel: ETCR025KMaterial: ABS+permalloyApplication: Electric power, communications, meteorology, railways, oil fields, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fieldsRange and Accuracy:RangeResolutionAccuracy ClassPhase ErrorTransformation Ratio0.00mA~30A AC0.01mA AC0.52 800:1Other Parameter:FunctionAC leakage current, high order harmonic current, phase, electric energy, power, power factor, etc. detectionDetection MethodOpen and close structure, no need to cut off the line under test without power failure, especially suitable for online installationCT SizeApprox. 25mm / 1inMeasuring Range0.00mA~30A ACTransformation Ratio800:1 (can be customized according to needs)Phase Error2Secondary Load 10ShieldingDouble layer shielding, suitable for complex interference environmentOutput MethodInductive current outputOutput InterfaceWiring terminal (S1, S2 coil tap end, GND shielding end)Frequency10Hz~100KHzSecurity LevelCAT600VExternal Size Approx. 78 x 82 x 31 mm / 3.1 x 3.2 x 1.2 inQuality Approx. 120g / 4.2ozOperating Temperature -15C~50CDielectric StrengthAC 3700V/rms (between iron core and shell).Package List:1 x Leakage Current Sensor
