Product Description

The YDBH0.66-40I-A-400/5A is a precision current transformer designed for energy measurement and monitoring systems. This YDBH0.66 current transformer features a primary-to-secondary ratio of 400/5A, supporting single-phase input with isolated analog output. Rated for 0.66kV AC systems, it operates within -25°C to +70°C, ensuring reliability in harsh industrial environments like power distribution, manufacturing automation, and renewable energy installations. The compact YDBH0.66-40I transformer offers ±0.5% accuracy with low power loss, optimized for DIN rail mounting. While lacking digital interfaces, its rugged epoxy-resin construction provides excellent insulation and vibration resistance. The integrated terminal blocks enable direct connection to protection relays or metering modules, eliminating need for external accessories. With IP54 protection and 2000V dielectric strength, this 400/5A current transformer delivers long-term stability for critical current measurement applications.
