This is a mini split base current transformer; it's the smallest one compared to the similar products (output 100MA). Fully enclosed, good mechanical properties and environmental resistance, strong voltage isolation capability, safety and reliability. Used for energy meter in special; AC 220V, 380V power supply can both be applied.           Features:       This is a mini split base current transformer; it's the smallest one compared to the similar products (output 100MA).       The diameter of inner hole is 16mm, the accuracy is ≤0.5 grade.       Using snap joint structure, it can be fixed to the cable directly through nylon ties.       Built-in input coil; small and light, easy to install.       Fully enclosed, good mechanical properties and environmental resistance, strong voltage isolation capability, safety and reliability.           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.           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.           Specifications:       Model: PZCT-02       Environment temperature: -40& 8451;~+85& 8451;       Relative humidity: ≤ 90%(40& 8451;)       Working frequency: 50Hz~60Hz       Insulation endurance grade: B grade (130& 8451;)       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       Size: 47x31x29mm/1.85x1.22x1.14"       Wire Length: 200mm/7.87"       Quantity: 1 Pc           Note:       Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid       Due to the difference between different monitors, the picture may not reflect the actual color of the item.
