Product Description

The CTF35-500A/5A is a high-precision CTF35 Current Transformer designed for industrial power monitoring systems. It features a primary input current rating of 500A and a secondary output of 5A, enabling seamless integration with energy meters, PLCs, or relay modules. Operating within 50/60Hz frequency and a voltage range of 0-690V, this 500A/5A Transformer supports direct connections to up to 3 auxiliary devices via screw terminals. Its rugged construction ensures reliable performance in temperatures ranging from -25°C to +70°C, suitable for power distribution, manufacturing, and renewable energy applications. With a compact design and 0.5% accuracy class, it offers low insertion loss but lacks native communication protocols like Modbus. The device requires no battery or screen, focusing solely on current measurement. Its detection distance aligns with standard DIN rail mounting requirements.
