Product Description

The CTF35-400A/5A is a high-precision CTF35 Current Transformer designed for accurate current measurement in industrial applications. With a 400A primary input and 5A secondary output, this 400A/5A CT Sensor is compatible with energy meters, relays, and monitoring systems, supporting direct integration with up to 3 modules simultaneously. It operates within a wide voltage range of 80-480V AC and a temperature range of -40°C to +85°C, ensuring reliability in harsh environments. Ideal for power distribution, renewable energy, and industrial automation sectors, the CTF35-400A/5A features galvanic isolation, compact design, and ±0.5% accuracy. While lacking built-in communication interfaces, its robust construction and linear response across 5-400A ranges make it suitable for load monitoring and protective relay coordination. The sensor requires no external power and delivers a detection distance of up to 50mm for non-invasive installation.
