Product Description

The YDBH0.66-40I Current Transformer (YDBH0.66-40I-A CT) is a precision 500/5A Current Sensor designed for low-voltage power monitoring, featuring a single input and isolated analog output for direct integration with energy meters or PLC modules. Operating within 0-0.66kV AC and -25°C to +70°C, it supports applications in industrial automation, renewable energy, and smart grid systems. This CT offers a compact design with 1.5% accuracy, simplified DIN-rail installation, and 20mm conductor detection range. While lacking onboard communication interfaces or displays, its robust construction ensures reliable performance in harsh environments. Compatible with standard 35mm rails, it requires no external power, making it ideal for space-constrained installations demanding accurate current measurement without complex setup.
