Product Description

The CTF35 Current Transformer, part of the 300A/5A CT Series, is designed for high-accuracy current measurement with a primary input rating of 300A and a 5A secondary output, compatible with standard monitoring devices. It features a single input channel and connects directly to energy meters, relays, or SCADA systems, supporting integration via RS485 or Modbus interfaces. Operating within a voltage range of 80-300V AC and a temperature span of -25°C to +70°C, it ensures reliability in harsh industrial environments such as power distribution, renewable energy, and manufacturing. The High Accuracy CTF35 delivers ±0.5% precision, making it ideal for load profiling and fault detection. Its compact design suits confined spaces, though installation requires careful alignment to avoid measurement drift. The absence of a built-in screen or battery emphasizes its focus on core measurement functionality.
