Features Dedicated to Electric Energy Meters: The inner diameter of the miniature open-close current transformer is 16mm, and the precision is ≤0.5, which is specially used for electric energy meters; both AC 220v and 380v power sources can be used. Buckle Structure: The open-close current transformer adopts a buckle structure, which can be directly fixed on the cable through nylon cable ties. Built-in Input Coil: PZCT-2 Miniature current transformer has a built-in input coil, which is small and light, easy to install, and has a stable and reliable structure. Split Current Transformer: This is a mini split current transformer, smaller in size (output 100MA) among similar products, easy to carry and store. Fully Enclosed Design: The AC current sensor transformer is fully enclosed, with precise mechanical properties and durability, strong voltage isolation capability, and relatively reliable. Specifications: Model: PZCT-02 Environment temperature: -40℃~+85℃ Relative humidity: ≤ 90%(40℃) Working frequency: 50Hz~60Hz Insulation endurance grade: B grade (130℃) Insulation resistance: >1000MΩ normally Dielectric strength: can afford power frequency 1000V/1minute Flame resistance: Conform to UL94-Vo grade Internal resistance: 10Ω  Measuring range: 0-100A Weight:59g Application: 1. The current transformer is used for energy meter in special; AC 220v, 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. Package Included: 1 x  Current Transformer  Note: 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 fuse. Package List
