Parameters: Environment temperature: -40?~+85? Relative humidity: never more than 90% when the temperature is 40? Working frequency: 50Hz~60Hz Insulation endurance grade: B grade (130?) Insulation resistance: more than 1000M? normally Dielectric strength: can afford power frequency 1000V/1minute Flame resistance: Conform to UL94-Vo grade Internal resistance: 42?    Test linear range: 0-100A 10A      secondary output: 10MA 50A      secondary output: 50MA 100A    secondary output: 100MA Ratio is 1000: 1   Range of Application: 1. The current transformer is used for energy meter in special; AC 220v, the 380v power supply can both be applied. 2. When you fix the energy meter, you don’t need to cut off the power if you use this product.   Precautions: 1. The CT primary should be connected in series with the test current loop, the secondary should be as work in the short-circuit state 2. The secondary circuit is not allowed open circuit, so please do not install a fuse. Package Including: 1x Current Transformer
