PZKHCT Split Base Current Transformer Coil Sensor for 100A Amp Energy Meter 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.
