Descriptions: 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.

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.
